Energy storage systems (ESS) can also be beneficial for load-levelling and peak-shaving, as well as reducing the ramping of generators. However, the optimal energy and power ratings for these devices is not immediately obvious. In this paper, the energy capacity and power rating of the ESS is optimized using two-stage stochastic optimization. In order to capture the wind and load variations in the different days throughout the year, it is advantageous to use a large number of scenarios. Optimizing generator outputs and storage decisions at the intra-hour level with a high number of scenarios will result in a very large optimization problem, and thus scenario reduction is employed. A relationship between the variance of the system price for each scenario and the optimal storage size determined for that scenario is shown. The correlation between these parameters allows for a natural clustering of similar scenarios. Scenario reduction is performed by exploiting this relationship in conjunction with centroid-linkage clustering, and stochastic optimization with the reduced number of scenarios is used to determine the optimal ESS size.","PeriodicalId":421766,"journal":{"name":"2014 North American Power Symposium (NAPS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124195749","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}

For several decades, the practice of CVR has been implemented in utilities and the reports indicate that such practices have resulted in annual energy savings up to a few percentages, depending on factors such as the nature of the loads, climate, geographical area, etc. With more penetration of renewable sources of energy, such as photovoltaic systems, questions arise on how Volt-VAr control using CVR can be impacted and/or improved. Furthermore, it is desired to understand the behavior of aggregated loads at the main substation of the distribution system in order to estimate the effectiveness of CVR. As such, an actual distribution feeder has been simulated at various PV penetration levels, with and without implementation of CVR, and its CVR factor density has been calculated using aggregated load modeling based on ZIP parameters. Our results indicate that the increase in PV generation weakens the constant power component of the aggregated load, thus increasing the CVR factor density.","PeriodicalId":421766,"journal":{"name":"2014 North American Power Symposium (NAPS)","volume":"20 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131958622","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}
