However, routing coordination of these resources with backup power can provide a reliable and economical electricity supply under different load demand conditions. This paper proposes the concept of routing in electrical networks to compensate for the energy deficit and manage the power transfer control in grid-connected and islanded modes. The coordination management of electrical energy resources in terms of active or reactive power is adopted using a routing matrix. A fuzzy approach is applied to realize the control mechanism from the routing topology perspective. The results show that the routing scheme meets the requirements of bidirectional power flow, where the balance of active power and the compensation of reactive power can be achieved.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"294 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116454907","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 primary difficulty for EV charging scheduling comes from the uncertainty associated with the arriving EVs, including their arrival time, departure time, and charging volume. This makes the scheduling in a single EV charging station already challenging. Clearly, the joint scheduling across different charging stations is even more challenging. To this end, in this paper, we first develop a risk-limiting charging scheduling approach based on chance-constrained optimization in the offline setting. To enable online charging scheduling, we propose a model predictive control (MPC) approach, which could effectively reduce the impact of forecasting errors. We numerically demonstrate that our approach can achieve near-optimal performance. Specifically, we empirically evaluate the influence of prediction error on the scheduling cost, which indicates the value of information in EV charging scheduling.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126552459","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 electrification ratio in Riau is only 99.82%, and not all have 24-hour access to electricity. Because it is located on the equator, Riau has abundant solar energy potential. It is estimated that 753 MW of solar energy can be generated in Riau. This paper aims to examine the potential of solar energy in Riau, including scenarios of solar energy generation based on its geographical characteristics. The most significant hazard, forest fires, and their impact on solar power generation are identified in this paper. SWOT analysis of solar power generation in Riau is briefly formulated to assist stakeholders in determining strategies for implementing solar energy generation in Riau.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127750676","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}

Therefore, in this section, the 100% PV penetration region in each interconnection is simulated to study the local high PV penetration effects. The study was performed by quantifying rate of change of frequency (RoCoF), frequency nadir, and settling frequency at different regional PV penetration levels. The impact of high regional PV penetration on the compliance of grid code on frequency response is also studied.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127277579","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}
