Supply and demand unbalance would lead to unstable frequency, in particular in isolated island systems, and system accidents would cause a serious situation. This work simulates the demand response that is applied in the isolated Penghu Island system, and a designed demand response is applied in the system every 1s. The result shows that demand response can effectively reduce the effects caused by accidents and improve system reliability and security. ","PeriodicalId":13951,"journal":{"name":"International Journal of Electrical Energy","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74164692","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 computational complexity will increase exponentially with the increasing number of hydropower plants, which is also called “curse of dimensionality”. Progressive optimality algorithm (POA) is a classical algorithm to relieve the problem, and it has been widespread utilized in OLHS. However, POA has an important precondition during OLHS, which neglects the benefit produced by water head variation. In order to solve the problem, an improved algorithm called double effects POA (DEPOA) which takes water discharge effect and water head effect into account is proposed. Finally, the proposed DEPOA is applied to the optimal scheduling of large-scale hydropower system in the Yangtze River basin. The results indicate that DEPOA can improve the total power generation of all plants when compared to POA, which fully verifies the effectiveness of DEPOA for OLHS.","PeriodicalId":13951,"journal":{"name":"International Journal of Electrical Energy","volume":"63 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72611829","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 this paper, to realize the coordination of hydropower stations and power grids, the minimum variance of residual load series which are obtained by subtracting hydropower generation from the original forcasting load of each power grid, is used as the optimization objective of QHGSHS problem. On this basis, considering the complementary features among multiple power grids, the adaptive differential bee colony optimization algorithm (ADBCO) with heuristic constraints repairing strategies is proposed to optimize the power allocation of the hydropower stations in Central China with the constraints such as electrical power transmission proportion, power balance of hydropower stations and power transmission limit of HVDC transmission line considered.

In this paper a practical setting method for the over-current relay considering the injected power is proposed. The proposed strategy is based on the bus maximum injected power, and the basic principle of the method is to prevent the over-current protection from maloperation when there has injection current or branching current. In addition, coordination between Grid Automatic Reclosing Time (GART) and photovoltaic (PV) Low Voltage Ride Through (LVRT) is also studied in this paper. By using exact experimental analysis, the grid maximum automatic reclosing time under common faults is given. Simulation results show that reclosing within the maximum reclosing time can guarantee the successful operation of LVRT for the PV, which would be a guiding value for the safe operation of large-scale Grid-Connected Photovoltaic (GCPV).","PeriodicalId":13951,"journal":{"name":"International Journal of Electrical Energy","volume":"2012 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87960435","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}
