In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will be reduced. In line with smart grid concepts, an association rule-based method is presented in this paper to find the outage cause. To do this, we have first combined outage, load, and weather datasets and extracted features. Then, for every cause, the records are labelled main class or others. The association rules are extracted and evaluated. Through these rules, one can determine if the outage has happened because of a fault in a certain piece of equipment or not. Doing so alongside using smart devices may lead to reliability enhancement.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134183373","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}

This flexibility should be supplied by different sectors and players of power systems. The role of demand especially prosumers in providing flexibility have recently been highlighted. In this regard, this paper presents a new flexibility-based algorithm for a Home Energy Management System (HEMS). The HEMS focuses on Electric Vehicles (EVs) and Electrical Energy Storage (EES) as main sources of flexibility products. Two main products, namely, positive and negative flexibility are defined as deviations from optimal energy schedules attained by the HEMS. Each flexibility’ offer related to the device is offered at a specific price in the flexibility platform. Final flexibility plans are extracted after running a linear optimization model. It has been shown that these products can properly enhance the flexibility level of distribution systems and simultaneously impose no additional cost for prosumers.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134641330","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}

Energy Storage Systems (ESSs) can be a solution to this issue but using them in a distribution network needs considerable investment. On the other hand, capacitors can enhance the voltage profile, reduce the power loss of the distribution network, and due to cheapness, reduce the total system cost. This paper presents a model for the optimal sizing problem of ESSs and capacitors in a distribution network. The model is multi-objective and formulated as a mixed-integer non-linear programming problem. The optimization problem is solved to minimize the total system cost and enhance the voltage profile using the Genetic Algorithm (GA). The simulation results on the IEEE 33-bus network show the effectiveness of this method.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131101608","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}

So as to reach this goal, in this research, different data-clustering methods based on machine-learning algorithms are tested whereby a hybrid forecasting engine composed of a search technique called Symbiotic Organisms Search (SOS) and Levenberg-Marquardt learning algorithm is proposed, aiming to increase the precision of short-term forecasting. In this approach, the adjustable weighting coefficients of the Artificial Neural Network (ANN) can be automatically fine-tuned using SOS. The efficiency and applicability of the proposed engine are analyzed and illustrated by its implementation on the EUNITE competition test case and thereby relevant conclusions are drawn to suitably demonstrate the merits of the proposed method.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133602224","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, the voltage profile level for a part of the Mashhad's residential distribution system has been simulated. First, real energy consumption data in the residential sector with a time step of one hour is calculated. In order to investigate the impact of different penetrations of different solar systems, generating power of single-phase PV panels with capacities of 6 and 10 kVA was extracted. To improve the voltage profile, adjusting the power factor of solar inverters and automatic control of transformer tap changers have been used. According to the obtained results, by applying the mentioned control methods, not only can the voltage profile be reduced by more than 7%, but also its stability can be better by reducing the network imbalance.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123193179","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}

However, a variety of inverters makes different choices for users of photovoltaic systems, that each has its own advantages and disadvantages. Therefore, it seems necessary to study multilevel inverters and their performance. In this paper, by studying different structures of multilevel inverters, the optimal structure in terms of structural complexity, electrical stresses on various components, cost, weight, losses and THD harmonic index for photovoltaic systems is presented. In order to identify the optimal structure, the most common multilevel inverters are compared and two main categories of inverter related indices and indices related to their performance have been studied. Matlab software is used to perform the simulations. The structures investigated are neutral-point-clamped multilevel inverters (NPC-MLI), flying capacitor multilevel inverter (FC-MLI) and cascade H bridge multilevel inverter (CHB-MLI).","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128926299","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}

As WAMS consist of various interdependent infrastructures, they imply complex cyber, physical and geographical dependencies among their underlying components. Although several existing works have studied these types of dependencies independently, there is a lack of a holistic approach that can simultaneously capture all different dependency types. The main goal of this paper is to examine the overall dependencies of WAMS infrastructures. We present preliminary results based on simple and well defined set of rules, that unifies cyber, physical and geographical dependencies of WAMS. Such a unified approach may support the design of WAMS infrastructures that are inherently more resilient to disruptions caused by different kinds of unwanted events such as cyber attacks (affecting cyber dependencies), faults (affecting physical dependencies) or natural disasters that may affect geographically dependent WAMS components.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124191257","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}

Discrete wavelet transform (DWT) is used to extract the hidden features of DGs parameters. Hidden features are the input of a deep neural network (DNN). The proposed scheme has significant accuracy in islanding detection, and it could be applied to different microgrids. We used three software to detect islanding events.

With the advent of microgrids and the expansion of distributed generation resources and also, the development of energy storage system technology, the role of energy storages are increasing. By the proposed control system, the battery energy storage system (BESS) participates in the microgrid energy management and also plays a role in voltage regulation and compensating for current harmonic, unbalance, and reactive power due to the presence of nonlinear loads. In this paper, fuzzy logic-based energy management is proposed, which considers the battery state of charge (SOC), matching between load and wind turbine unit power curves, and the cost of purchased or injected electricity into the grid. In the proposed control system, the limitation of inverter in reactive power injection and the battery's protection from over-charge and over-discharge is also considered. To validate the application of the proposed control system, simulations are performed in MATLAB/Simulink software. The simulation results confirm and prove the efficiency of the proposed control system.","PeriodicalId":391511,"journal":{"name":"2020 10th Smart Grid Conference (SGC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124384421","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}
