Hydro power generation with water reservoir has favorable dispatch flexibility that can be used to mitigate the intermittency and uncertainty of photovoltaic. Hydropower and photovoltaic can be coordinated by storing water energy in the peak hours of solar and shifting it to off-peak periods. In this paper, a metric of dispatch flexibility is defined to evaluate to what extent the solar and hydro generation can be coordinated. The methodology for measuring the dispatch flexibility of solar-hydro coordination is proposed based on a multi-scenario dispatch model considering the uncertainty of water inflow and solar irradiation. Results are drawn with a study on the first and largest solar-hydro coordination project in China, the Longyang Gorge (LYG) project. The study quantifies the generation dispatch flexibility of LYG project and illustrates the potential impact of different factors on solar-hydro coordinated generation.","PeriodicalId":155315,"journal":{"name":"2016 IEEE Power and Energy Society General Meeting (PESGM)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127335162","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 was determined that the transient voltages during prestriking could have large differential values which could put much more switching stress on the nearby circuit breaker and other equipment.

This paper assesses PAR versus cost tradeoff when scheduling an electric vehicle (EV) fleet. We formulate a bilevel Mixed-Integer Linear Programming optimization problem. At the lower level, we minimize individual household electricity bills using dynamic pricings. At the upper level, we aim to smooth the power load curve of a typical Brussels MV/LV transformer. We show that a small deviation from cost-only optimization can reduce significantly the Peak-to-Average Ratio of the power load curve of a transformer. Harnessing load flexibility from EV allows the DSO to manage the transformer load to avoid grid congestion and also incentivizes load aggregators to participate in the ancillary services market.","PeriodicalId":155315,"journal":{"name":"2016 IEEE Power and Energy Society General Meeting (PESGM)","volume":"108 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130547078","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 model of photovoltaic (PV) inverter is presented as state space equations with DPSCs. The unbalanced fault condition can be given as the input vector in the state space equations. With supposing the states of the inverter controller keep constant during the subtransient period, then the state space equations can be solved and the fault current on ac side and the dynamic performance of the voltage on dc side can be calculated. With comparison of the simulation results, the model of PV inverter based on DSPCs can obtain the fault currents under different operation conditions.

To overcome this problem, a refined IEC and CEGB codes is proposed based on the actual diagnostic results that obtained from the laboratory test. 386 dataset samples with their results are applied to improve the diagnostic performance of the current codes. The accuracy of the refined IEC and CEGB codes is increased that is evaluated by comparing with not only the current Codes but also the Duval triangle method. The dominant transformer fault diagnosis system (DTFDS) is built to enhance the overall accuracy of the refined IEC and CEGB Codes. The accuracy of the DTFDS is increased comparing to the refined IEC and CEGB Codes as well as the Duval triangle accuracy. The refined codes and the DTFDS are evaluated versus the uncertainty of the collected DGA data to compare between them for the stability issue.
