The existing DR schemes in the literature mainly focus on optimizing customer’s load profiles but not enough attentions are paid to important factors such as energy consumption patterns of residential appliances, electricity cost, users’ satisfactory level, fairness and energy consumption habits. This paper proposes a flexible DR scheme in smart grid with clustering of residential customers and comprehensively considering the aforementioned factors. New features are extracted from historical data to depict customers’ characteristics and clustering methods are applied to explore their electricity consumption habits. Then such information is further utilized to help schedule the residential appliances in a more flexible but effective manner. Numerical results based on real-world traces demonstrate that the proposed DR scheme performs well in reducing the system expenditure and lowering peak to average ratio (PAR). Our research further analyzes the impacts of various factors, including customers’ preferences and energy consumption patterns, which sheds some illuminations on how to devise efficient DR strategies.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134149469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

VVC not only keeps voltages in the distribution system within desirable ranges but also reduces system operation costs, which include network losses and equipment depreciation from wear and tear. In this paper, the deep reinforcement learning approach is taken to learn a VVC policy, which minimizes the total operation costs while satisfying the physical operation constraints. The VVC problem is formulated as a constrained Markov decision process and solved by two policy gradient methods, trust region policy optimization and constrained policy optimization. Numerical study results based on IEEE 4-bus and 13-bus distribution test feeders show that the policy gradient methods are capable of learning near-optimal solutions and determining control actions much faster than the optimization-based approaches.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116080830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The indices of the transmitters, which are light emitting diodes (LEDs) are coordinated by antenna matrices using permutations. Therefore, each index is selected only once at each transmit time and transmit block. However, the maximum likelihood (ML) detection becomes complex as the size of the LEDs increase and the STSK scheme requires knowledge of the channel state information (CSI). The proposed SD receiver uses the soft information from the channel to detect the likely transmitted symbols by interpreting the channel output as an assignment problem. The proposed receiver is capable of estimating the likely transmitted symbols with or without the knowledge of the CSI. Results are shown comparing the bit error rate (BER) of the ML receiver with perfect knowledge of the CSI with the SD receiver. The SD receiver matches the ML in cases where higher data rates are required and CSI is known but shows a 5dB loss without the knowledge of the CSI.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116599853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, these opportunities also introduce some essential challenges. One of these challenges is the voltage stability management in a distribution network such as Microgrids. To address this challenge, in this paper, we develop a decentralized voltage management mechanism in the form of an augmented optimal power flow (OPF) problem. In our work, the OPF problem is further decomposed and is solved by exploring the alternating method of multipliers (ADMM). Additionally, reactive power reserves (RPRs) are utilized to generate$/$inject the necessary reactive power at each bus to stabilize the voltage locally and to curb any possible disturbances in the voltage performance. Furthermore, in our work the impact of the communication delay caused by the decentralized management has been considered and mitigated. In this paper, a customized radial 9-bus single feeder distribution network has been used to demonstrate our work. The simulation results have been presented to illustrate the performance of our work.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121879488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inherent features of renewable energy, including the fluctuation in the amount of electricity generated and the time at which electricity can be generated, call for the need of large energy storage systems. Drastic changes would be required not only in the architecture but also in the business models of electricity supply systems. We propose a platform called a “virtual grid system” as a foothold originating from a disruptive innovation strategy to create renewable-energy dominant infrastructures. The system is designed for powering systems comprising IoT devices connected by USB Type-C cables with power delivery protocol (USB-C PD) and for replacing the proliferating primitive off-grid solar systems to provide electricity access to more than 360 million people worldwide. The virtual grid system dynamically creates a power distribution subsystem called a “virtual grid” to be included in an IoT application system. It controls electric flows from power source devices to be synthesized and distributed to load devices in the virtual grid via hub devices called “virtual grid hubs (VG-hub).” A method is developed to control electric flows with concise demand descriptions, and it achieves an optimized flow setting over VG-hub networks using graph theoretic algorithms. A distributed implementation of the virtual grid hub is discussed to increase the distributable power, while the current virtual grid hubs handle too small power for main stream power customers.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121913779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Domain-Adversarial Transfer Learning for Robust Intrusion Detection in the Smart Grid 面向智能电网鲁棒入侵检测的域对抗迁移学习

{"title":"Domain-Adversarial Transfer Learning for Robust Intrusion Detection in the Smart Grid","authors":"Yongxuan Zhang, Jun Yan","doi":"10.1109/SmartGridComm.2019.8909793","DOIUrl":"https://doi.org/10.1109/SmartGridComm.2019.8909793","url":null,"abstract":"The smart grid faces growing cyber-physical attack threats aimed at the critical systems and processes communicating over the complex cyber-infrastructure. Thanks to the increasing availability of high-quality data and the success of deep learning algorithms, machine learning (ML)-based detection and classification have been increasingly effective and adopted against sophisticated attacks. However, many of these techniques rely on the assumptions that the training and testing datasets share the same distribution and the same class labels in a stationary environment. As such assumptions may fail to hold when the system dynamics shift and new threat variants emerge in a non-stationary environment, the capability of trained ML models to adapt in complex operating scenarios will be critical to their deployment in real-world smart grid communications. To this aim, this paper proposes a domain-adversarial transfer learning framework for robust intrusion detection against smart grid attacks. The framework introduces domain-adversarial training to create a mapping between the labeled source domain and the unlabeled target domain so that the classifiers can learn in a new feature space against unknown threats. The proposed framework with different baseline classifiers was evaluated using a smart grid cyber-attack dataset collected over a realistic hardware-in-the- loop security testbed. The results have demonstrated effective performance improvements of trained classifiers against unseen threats of different types and locations.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130170216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present the retail electric provider’s (REP) optimal pricing strategy for residential customers in smart grid, in which the REP offers multiple utility plans for customers with different needs, which includes a flat-rate plan, a multi-stage plan, and a lump-sum fee plan. The residential customers select the utility plan that maximize their own payoffs by considering their own demands and the pricing strategies of the three plans. In the other way around, the REP optimizes its profit by carefully designing its pricing strategy based on residential customers’ decisions. To obtain insights of such a highly coupled system, we consider a system with one REP and a group of customers in need of electricity. We propose a three-stage Stackelberg game model, in which the REP acts as the leader who decides the specific plans to offer at Stage I, then announces the price for each plan in stage II, and finally the customers act as followers that select plans in stage III. We derive the market equilibrium by analyzing customers’ decisions among the plans under different pricing schemes. Then, we provide the RP’s optimal pricing strategies to maximize its profit. In the end, we give the optimal decisions for REP on the specific plan(s) to offer while considering each customer’s evaluation and demand. Both the analytical and simulation results show that the lump-sum fee plan can maximize RP’s profit in most cases.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128790947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of modern or smart grids, the control signals, i.e., the tap change commands are sent through SCADA channels. It is well known that the power system SCADA networks are prone to attacks involving injection of false data or commands. While false data injection is well explored in existing literature, attacks involving malicious control signals/commands are relatively unexplored. In this paper, an algorithm is developed to detect a stealthily introduced malicious tap change command through a compromised SCADA channel. This algorithm is based on the observation that a stealthily introduced false data or command masks the true estimation of only a few state variables. This leaves the rest of the state variables to show signs of a change in system state brought about by the attack. Using this observation, an index is formulated based on the ratios of injection or branch currents to voltages of the terminal nodes of the tap changers. This index shows a significant increase when there is a false tap command injection, resulting in easy classification from normal scenarios where there is no attack. The algorithm is computationally light, easy to implement and reliable when tested extensively on several tap changers placed in an IEEE 118-bus system.","PeriodicalId":377150,"journal":{"name":"2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127711574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The charging station receives multi-type battery orders from the demand side, and it can refuse the orders or admit part of the orders according to current system states. If admitted, battery orders have to be served completely before predefined deadlines. Based on Lyapunov optimization framework, a dynamic scheduling approach is developed, which allows the charging station to observe real-time system states and make scheduling decisions in an online fashion. In theoretical analysis, the feasibility and suboptimality of the proposed approach are proven. Based on the analysis, the feasible ranges of algorithm parameters are derived, ensuring that battery orders can be completed before deadlines. In simulation, actual real-time electricity data is used.
