The proposed approach analyze the solar and wind potential of the substation locations to determine the substations having the ability to deliver the maximum energy. In order to do it, existing weather data is utilized to calculate the average energy that can be generated in the substations. And for an optimal choice, Multi-Criteria Decision Making (MCDM) is used to evaluate and compare the different criteria. The results open the way to choose the appropriate substation to implement the microgrid and ensure that the energy supplied by the wind and the solar satisfies the energy needs of the substation.

High penetration levels of DERs and random EV charging behaviors may cause additional voltage violations that are difficult to handle with classical voltage regulation devices. Fortunately, advances in power electronics facilitates using inverter-based DERs to provide reactive power support alongside existing regulation devices. Yet, controlling large number of inverter-based DERs can be challenging due to the increased communication requirements and control cost. This paper proposes a new dynamic system voltage influencer (SVI) paradigm that identifies the most suitable inverter-based DER assets that must be engaged in the voltage control program. SVI nodes are based on existing system topology and temporal changes in local load, DER, or EV patterns. Therefore, the proposed approach ranks the SVI nodes and uses the most influential nodes for voltage control applications. The proposed approach is verified via simulations on the IEEE 37 node test system. In addition to eliminating voltage violations, results show that it is possible reduce the cumulative control cost using the proposed dynamic SVI approach.","PeriodicalId":288300,"journal":{"name":"2023 5th Global Power, Energy and Communication Conference (GPECOM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108838","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}

Electric vehicles and a hydrogen-based energy storage unit including a fuel cell unit can have a special capability in energy management. In this article, the problem of determining the selling price and managing the energy resources for a retail intermediary agent in the smart grid under the influence of the existing uncertainties is investigated. In this study, the impacts of the presence of several generation companies (GENCOs) in a wholesale pool market structure incorporating bilateral contracts are considered while the fossil-fuel-based small-scale distributed generation units, electric vehicles aggregators, renewable energy sources (PV and WT), and hydrogen-based storage systems are supposed to participate in the retail market level. Moreover, the uncertainty of pool market prices, load profile, the intensity of sunlight and temperature, and wind speed are modeled using the Monte Carlo method. The optimization problem aims to maximize the retailers’ profitability and to determine the optimal strategy of retailers in different levels of electricity markets using the gorilla troop optimization method.
