As China national economy and technology are under rapid development, all industries are requesting better and better quality of electrical energy. Therefore, research on technology for quality regulation and control of electrical energy of power distribution network becomes first priority. The optimized algorithm of controller as stated in this article for quality regulation and control of electrical energy is optimized double closed-loop control algorithm which enables system to have better stability and control accuracy while ensuring quick dynamic response. During test, an optimized d-p detection algorithm is adopted. Such new algorithm is also applied for detecting harmonic in power distribution network. Then general detection accuracy is efficiently improved.
