Due to this aspect, in this paper the effects of enhanced penetration level of renewable energy sources (RESs) are investigated regarding the system dynamics. The voltage stability is examined in detail based on the Nordic Test System. As a result of the enduring change in power systems, the risk of blackouts caused by voltage instability increases. Therefore, an indispensable need for a test system arises that is capable of simulating such voltage instabilities in the presence of inverter-based generation. Due to the lack of a publicly accessible test system that incorporates inverter-based generation, the well-documented Nordic Test System has been modified to achieve a share of 35% of renewable sources. Various simulation results show that the proposed modified system has a more pronounced voltage gradient compared to the original one. It also has similar long-term dynamics that is depending on the selected current limitation. For complete transparency, all individual modifications are presented and explained in detail.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132044759","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 fact, the Mid-continent Independent System Operator (MISO) has characterized uncertainties (e.g. load growth, carbon emission reduction, renewable portfolio standards, investment costs) to construct future scenarios that are studied in the long-term planning process. Therefore, MISO takes a scenario-based approach to identify optimal resource investment portfolios. This provides the opportunity to implement an adaptive expansion planning (AEP) framework to MISO's scenario-based planning process. The AEP model is a stochastic-based expansion planning model that seeks to minimize the net present value of the investment and operation costs within the generation and transmission systems. The AEP model identifies core and adaptive investments designed to provide a flexible investment portfolio over the planning horizon for all planning scenarios under study. This paper presents optimal investment portfolios from the AEP model and discusses implications to how the AEP model can benefit the MISO planning process.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117125136","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}

Although utilization of the PV resource offers many economic and environmental benefits, it can lead to some operational challenges for the power grid. These may for instance consist of power and voltage fluctuations, voltage flicker, and/or overvoltage instances. Regulation of voltage and reactive power has traditionally been achieved in the power grid through voltage and var control (VVC) applications, where substation transformer on-load tap changers (OLTC), voltage regulating transformers, and shunt capacitors are controlled in order to maintain an acceptable voltage profile across the network and/or minimize system losses. When PV penetration level increases, the energy resource can no longer be ignored in the operation of the power system and needs to be coordinated with other voltage control devices, thus necessitating a unified framework for voltage, var, and watt control (VVWC). Proposing one such solution is the objective of the current paper. A methodology has been proposed for VVWC based on a mixed-integer nonlinear multi-objective optimization problem, which is solved by utilizing goal programing approach in order to guarantee Pareto optimality of the solution. Three objective functions have been considered, namely minimizing active power curtailment of PVs, minimizing system losses, and conservation voltage reduction. The proposed method is applied to a modified version of the IEEE 123-bus test distribution system to validate its effectiveness.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130262589","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 paper analyzes the EV integration impacts on the distribution grid that mainly consists of residential loads. The EV uncertainties are addressed by a comprehensive model using arrival time and miles traveled. The penetration of EV is modeled based on the maximum permissible number of customers that can be connected to each node of a representative residential feeder. The temporal power consumption of EVs is calculated by using their daily trip and capacity information which are measured by utilizing specific EV models. An IEEE 123 bus feeder is used for power flow simulation and the demonstration of different case studies. Results from the customer-oriented modeling presented here show that wide voltage deviations occur at local nodes with higher penetration of EVs and it also depends on the distance of the nodes from the substation. The coincidental peak can cause large voltage unbalance at the closer nodes and hourly voltage profiles can vary significantly based on this. While voltage deviation increases with higher EV penetration at the distant nodes, the closer nodes demonstrate insignificant change in voltage deviation for different levels of penetrations. The synergy between EV and grid modeling and the in-depth statistical analysis of voltage distribution at the local nodes are needed by the grid operators for higher EV integration in the future.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"160 37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125990929","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}
