Research On Rapid Location Of Demand Response Resources

With the rapid development and pilot application of demand response in China,demand response has become an important means of peak-shaving and valley-filling in modern power grid.But its rapid development also brings some problems.For example,the power load involved in demand response projects will become more and more,and the number of demand response resources will increase dramatically.Because demand response in China is still in the transition stage from manual demand response to automatic demand response,the rapid growth of demand response resources may reduce the efficiency of demand response project implementation.The research on demand response resource management can play a very important role in the transition stage or even in the automatic demand response stage,and improve the efficiency of demand response project execution.According to the current research of demand response,this paper focuses on improving the efficiency of demand response management and fast query of demand response resources.Firstly,the research status of demand response at home and abroad and the research status in the field of scientific research has been investigated.Secondly,according to the research status of demand response at home and abroad,the demand response resources are classified,the address pool of multi-user demand response resources is designed,and the demand response resource mask is designed to deal with the problems caused by the rapid growth of demand response resources.Thirdly,in order to reduce the execution time of demand response projects and improve the execution efficiency of projects,based on the characteristics of demand response resources,a fast query method of demand response resources is studied from the perspective of graph theory.There are three main query methods:query method based on sequence length,query method based on binary Trie tree and query method based on binary Trie tree branch compression.Finally,In order to better adapt to the transition from demand response to automatic demand response,a multi-bit query method based on clustering binary Trie tree is proposed to improve the query speed of demand response resources by combining the resource address pool of demand response with the fast query method of demand response resources.
