Abstract

In recent years, many studies have been made to allocate NAS batteries in distribution substations for making good use of facilities and improving the load factor. Besides, it has been also hoped to utilize NAS batteries for the controls such as LFC and VQC, because NAS batteries can respond faster than existing generator units and can control active and reactive power outputs independently by the function of AC-DC converter systems. This paper presents a method for determining the optimal allocation and PQ output ratio of NAS batteries in order to improve voltage stability. The proposed method combines a sensitivity method with an OPF method, and can determine the allocation and PQ output ratio efficiently and optimally. Simulations are carried out for Ward & Hale 6-bus system and 73-bus distribution system to illustrate and verify the proposed method.
