Unlike wind power, the available output power of PV-systems can be classified into two specific time periods: certainly unavailable during the night and uncertainly available during the day. In other words, during the night, the output power is zero while during the day the output power experience uncertainties due to, among others, clouds and humidity. Therefore, this mixed behavior cannot be modeled as a stochastic variable during all time periods. The output power of PV-systems is clustered into bands and convolved with the output power of the conventional generators to determine the reliability indices and the capacity value. The IEEE RTS is used to demonstrate the effects of different strategies in calculating the capacity values of PV-systems. The results not only show that the capacity value is different for the two case scenarios but also the it decreases in a semi-linear manner as the size of the PV-system increases. Sequential Monte Carlo simulation is utilized to validate the results.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129173258","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 the integration presents a lot of benefits, satisfying the needs of local load requirements by reducing the line losses and facilitating congestion management, the problems of power quality that impact the distribution system become a priority. IEEE 519 describes network resonance as a major contributor impacting harmonic levels. LC and LCL filters on the AC side of PV Solar (PV) inverters that are designed to mitigate higher order harmonics tend to interact with the impedance of the entire network by exciting the harmonic resonance modes. Apart from that, wind based induction generators and induction motors are associated with terminal capacitors for voltage support. The interaction of such capacitive elements of distributed generators with the entire system impedance also impact resonance modes. To witness the impact of DG's, a control scheme for a 1.25 MW PV inverter based on hysteresis control with a simple LC filter is designed. This paper will serve as a reference for planning engineers and researchers working towards power quality by addressing the impacts of PV with distribution systems.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115830414","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}
