1. Introduction As distributed energy resources (DERs) including rooftop photovoltaics (PVs) and electric vehicles (EVs) become increasingly integrated into power systems, contemporary distribution networks now face unprecedented hurdles in maintaining stable voltage regulation [1, 2].
Distribution network contains a number of DESSs, if they are in a chaotic state, it cannot play the role in voltage regulation. Therefore, the main challenge using DESSs to regulate voltage is how to coordinate DESSs reasonably and determine the output power [11, 12].
The traditional methods of voltage regulation are not suitable for active distribution system because of the access of PV plant. This paper presents a method of voltage regulation by DESS. The main conclusions are as follows:
Secondly, a method is proposed to divide the voltage regulation area by calculating and comparing the voltage sensitivity matrix. On this basis, coordinated control sequence of DESSs and the model of the energy storage system is established.
