接入主动配电网的小水电与冷热电联供系统协同控制
Coordinated Control of Small Hydropower and CCHP Integrated into Active Distribution Network
摘要
Abstract
Water and gas resources are rich in the southwest of China,but it is difficult to connect distributed renewable resources,such as small hydropower(SHP) and combined cooling heating and power(CCHP),to the distribution network.To meet this challenge,the mathematical models and operation characteristics of SHP and CCHP are well studied,and a coordinated control and optimization approach for SHP and CCHP integrated into distribution network is proposed.In grid-connected mode,dispatched power is allocated between SHP and CCHP based on the equal increamental principle.In isolated mode,with the advantage of faster response speed,CCHP is used to assist SHP for primary frequency regulation when load fluactuation occurs.With overall considerations of cooling,heating and power load demand,not only the consumptive ability for distributed energy resources (DER) and overall operation economy is improved,but also it can provide support to distribution network with SHP or CCHP when abnormal condition or maintenance plan is encountered,and hence the reliability of power supply is improved.关键词
