The most immediate of these is that the voltage at the point of connection with vary depending on the power supplied to the network and may cause it to exceed statutory limits. This paper describes a new control scheme for a distributed generator that ensures that it supports the voltage control within the network and thus enables the distributed generator to contribute to network voltage management. The schemes performance is demonstrated using a detailed model of a distributed generator connected to a distribution network. It is shown that using this new control scheme, the distribution networks voltage constraints are maintained while maximizing the active power delivered by the distributed generation.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"54 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117172900","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}

Aimed at overcoming the defects of the general switching-operation system, which is weak in versatility and user maintenance, this paper has proposed a smart switching-operation system based on external knowledge base. We introduce the Cfront compiling idea into the system, and develop a kind of program language called rule language in order to program switching-operation rules. Users can use rule language to program or add new rules. The system translates these external rules into C++ source code through a translation function Function CompileRule(). Therefore, in the form of rule language, switching-operation rules can be stored out of the program instead of in the source code, which makes it convenient to expand, modify and maintain the knowledge base without modifying the source code. This greatly improves the versatility and maintainability of the switching-operation system.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125304908","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}
