However, some technical issues such as intermittent behavior of Renewable Energy Source (RES) and its reliability should be taken into account. In this paper, a hybrid PV/Wind system combined with hydrogen ESS system is compared to one with battery storage. Multi-objective Particle Swarm Optimization (MOPSO) is employed to size system components in order to supply the load of an autonomous microgrid considering cost and reliability indices. In this problem, photovoltaic arrays and wind turbines are subject to failure. Moreover, to increase the accuracy of calculation, the annual load, wind, and solar profiles from NREL (Illinois, USA) are applied to the optimization problem. A comprehensive cost function is defined to cover the capital, replacement, operation and maintenance costs as well as the number of replacements and interest rate during the project period (20 years). To increase the reliability of a stand-alone system as well as customer's satisfaction three reliability indices i.e., Loss of Energy Expected (LOEE), Loss of Load Expected (LOLE), and Equivalent Loss Factor (ELF) are taken into account. Results reveal that the proposed method can find the best configuration for both fuel cell/ battery based ESS system with the highest reliability and the lowest cost.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128220283","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 penalty functions are developed for total DG penetration limit, total reactive power injection limit, real power loss reduction target and voltage profile improvement. The fuzzy multi-objective function is formulated by developing the fuzzy membership functions for each penalty function considered for performance improvement. Ant colony optimization technique is used for obtaining the optimum size of DG units and shunt capacitors in order to achieve the predefined performance.

In this paper, the experience of Indonesia's South Sumatra blackout on July 23, 2018 is studied and presented. The blackout is reproduced and simulated, then validated with actual data. The root cause of the blackout is analyzed.

The new mechanisms, called the Value of Distributed Energy Resources (VDER), alter the value proposition of potential installations. In particular, multiple time-of-generation based pricing alternatives were established, which could lead to potential benefits from pairing energy storage systems with solar installations. This paper presents the calculations to maximize revenue from a solar photovoltaic and energy storage system installation operating under the VDER pricing structures. Two systems in two different zones within the New York Independent System Operator area were modeled. The impact of AC versus DC energy storage system interconnections with solar generation resources was also explored. The results show that energy storage systems could generate significant revenue depending on the pricing alternative being targeted and the zone selected for the project.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"42 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133183500","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 the first layer, each MG conducts an optimization individually for the day-ahead unit commitment with the objective of cost minimization. In the second layer, the MGs cooperate with each other to result in an effective PSTC management. The proposed operator in this paper, named microgrids aggregator (MGA), supervises the cooperative mechanism of MGs such that 1) purchased power from the distribution system operator (DSO) is minimized to result in congestion management of substation transformer (ST), 2) reliance on fossil fuels is controlled to prevent excessive CO2 emission, 3) sensitive data of each MG is only shared with MGA and other MG operators will have no access to such information. Finally, in the third layer, DSO receives the modified schedules from MGAs to ensure no technical constraint in the entire system is violated. If such a violation exists, a mandatory load shedding will be implemented by DSO. The effectiveness of the introduced framework is validated on the 33-bus IEEE distribution network modified with diesel-engine distributed generation (DEDG) units, wind turbine DGs (WTDGs), photovoltaic DGs (PVDGs), and electric vehicles (EV) stations.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116151114","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}

It aims to minimize the total cost of operation/generation of microgrids while meeting all the defined constraints. Since microgrids consist of distributed generators, it is imperative for these generators to communicate seamlessly with each other without any losses and to ensure secure operation of the microgrid. With use of distributed generators, noise is inherent in the system. Most of the economic dispatch problems do not include noise in their analysis while finding a relevant solution. This paper focuses on including noises as a constraint in grid connected mode microgrids to find a better economic dispatch solution. This will enhance the microgrid's performance and make it a more resilient system.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125810520","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}

It is demonstrated that phase steps are interpreted as sharp changes in frequency. The paper studies whether the location of the phase step, within the sinusoidal waveform, has any effect on the frequency estimate. Because phase steps are not the product of a permanent change in the underlying frequency, the paper proposes an algorithm to correct frequency estimates deemed erroneous. The algorithm makes use of the residual of the KF to determine when an estimate is incorrect and to trigger a corrective action in which the frequency estimate is replaced by an average of the previous values that were considered accurate. Using synthesized and simulated data with distortions the paper shows the effectiveness of the correction algorithm in fixing frequency estimates.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130238414","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}
