The solar heat energy utilization systems are rapidly gaining acceptance as some of the best solutions for the alternative energy sources. However, thermal energy collection of solar heat energy utilization system is influenced by solar radiation and weather conditions. In order to control the solar heat energy utilization system as accurate as possible, it requires method of solar radiation estimation. This paper proposes the thermal energy collection of solar heat energy utilization system based on solar radiation forecasting at one-day-ahead 24-hours thermal energy collection by using three different NN models. The proposed technique for application of NN is trained by weather data based on tree-based model, and tested according to forecast day. Since the tree-based-model classifies the meteorological data exactly, NN will train the solar radiation with smoothly. The validity of the proposed method is confirmed by computer simulations by use of actual meteorological data.","PeriodicalId":131589,"journal":{"name":"2009 Transmission & Distribution Conference & Exposition: Asia and Pacific","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115655599","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}

Micro-grids are concepts of distribution system that unifies directly with customers and distributed generations(DGs). It could supply the electric power to customers and do the power transaction using a power market by operating the economic dispatch through several DGs of diverse cost function. If there are a large number of micro-grids in one distribution system, it needs to adjust the configuration of many micro-grids in order to supply the electric power with the minimum generation cost to all customers who are under the distribution system.
