Due to the variable nature of these sources, new challenges have arisen in the daily operation of power systems. To cover these challenges, it is essential to increase the flexibility of power systems. Electrical vehicle parking lots (EVPLs) and demand response (DR) are introduced as two important solutions to provide a more flexible power system. To this end, this paper proposes a transmission constrained unit commitment based on AC power flow model (AC-TCUC) to minimize the daily cost of the integrated power system with EVPL, incentive-based DR and wind power. Additionally, an information gap decision theory (IGDT)-based robust approach is applied to handle the uncertainty of wind power production as a bi-level optimization problem with no need for probability distribution function (PDF). Numerical results illustrate the impact of EVPL and DR technologies on system operation cost reduction and the uncertainty of wind power.","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124704260","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, customer outage costs reduction is aimed through the optimal simultaneous placement of manual and remote-controlled switches (RCSs). Network reconfigurations are constrained such that operational considerations like statutory ranges for voltage levels, lines' thermal capacities, and necessity of radial configuration be conserved. Total cost reduction is mathematically modeled in a mixed-integer linear programming (MILP) model that makes the global optimal solution accessible. The validity of the proposed model is evaluated on the IEEE 33-bus network. In this study, investment cost of switches and damage cost of customers are considered as two objectives where Pareto front is derived for decision-making purposes.","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115587839","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}

Hence, this paper intends to present an optimal operation and energy management method for a hybrid micro-grid with study on day-ahead scheduling. In this paper, optimal operation of hybrid micro-grid including of photovoltaic, pump as turbine system, and diesel generator are considered. The optimal energy management minimize the fuel cost of diesel generator, annual operating cost as well as the balance between generation and load in different seasons. Aiming to this purpose, three famous optimization algorithms, namely artificial bee colony (ABC), particle swarm optimization (PSO) and imperialist competitive algorithm (ICA), are used to determine the optimal diesel generator generation, pumped storage operating mode, pumping and turbine real power in order to minimize the total operating cost for a day-ahead.","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124870501","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, a decentralized control method for charging coordination of PEVs associated with networked parking lots is proposed. Given that PEVs are distributed at different parking lots, we can consider each parking with its PEVs as a population and model the whole problem as a multi-population network. The aim of each PEV is to find the optimal charging profile so that its cost function is minimized, subject to the constraints. Due to the presence of the price as an aggregative term in the cost function of PEVs, the interaction among PEVs can be modeled as an aggregative game. By taking the advantage of this type of the game, a decentralized algorithm based on the consensus protocol and the Picard-Banach iteration is proposed. No information exchange is taken place among the PEVs and each PEV only communicates its charging power to its local parking lot coordinator and receives the price signal from that coordinator. It is shown that the proposed algorithm converges to the ε-Nash equilibrium point of the game, while ε uniformly converges to zero as the number of the PEVs goes to infinity.","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129588926","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}

Data with such quality acquired from a bidirectional infrastructure is a highly instrumental in increasing energy awareness in smart cities. The bidirectional communication infrastructure provided by AMI increases the customers' awareness about their consumption behavior, too. One of the issues affected by considering AMI in distribution network is demand side management (DSM). The accurate customer characterization using AMI data is a practical point in increasing energy awareness in the smart cities. The role of AMI in DSM programs is embossed when customers are regarded as influencing participants in these programs. This paper proposes a procedure investigating the role of AMI in improving demand response (DR) by costumer characterization in distribution network. Authors believe that DR is suitably implemented in distribution network if the analysis of customers' consumption behavior is conducted accurately. Besides, customers' capacities for participating in DR are different which is unfold by analyzing their consumption behaviors. Customers' consumption that are recorded by smart meters in different time slots compose time series on which pattern recognition procedures are applied. Different time series are clustered on the basis of their similarities and DR is implemented on each cluster separately. In This study, DR is implemented in two years in one of which capacities of each cluster for participation in DR is estimated and in another one these capacities are compared with the observed capacities. The results of this study confirm the accuracy of the estimated capacities and the proposed method. This knowledge helps the networks' operators to get a more accurate overview on the total capacity of the distribution network for implementing DR. The proposed method is implemented on a real dataset provided by Irish social science data archive (ISSDA).","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123552348","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 Printed Circuit Board Rogowski Coil (PCBRC) sensor is utilized to detect the arc flashes resulting from the faults occurring at any level of the Photovoltaic (PV) system. Two PCBRCs are connected in electrically opposite directions to cancel the undesirable influence of any noise source. The sensors are located at the positive and negative feed conductors at the inverter-end side. Upon the arc fault occurrence, a transient AC current passes through the Current-Carrying Conductor (CCC) which is sensed by the PCBRC sensor. The measured signal is amplified and latched by a dual ultra-fast voltage comparator in the first step. Then, a microprocessor is activated, which performs multiresolution analysis on the measured signal in order to confirm or reject the initial decision. The effectiveness of the proposed method is confirmed by different experimentations.","PeriodicalId":182699,"journal":{"name":"2019 Smart Grid Conference (SGC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126970242","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}
