Abstract

With the rapid development of distributed photovoltaic industry and sustaining improvement of photovoltaic penetration of low-voltage distribution network

voltage safety control is very difficult. In this paper

the network loss and voltage characteristics as well as operation cost of low-voltage distribution net-work with high-penetration photovoltaic is analyzed

and the active voltage control model of low-voltage dis-tribution network with consideration of both voltage safety and operation economy is proposed. The modeltakes minimum operation cost as optimization control objective

on the base of traditional voltage controlmethod

expands control measures of photovoltaic power factor and energy storage active power

considersthe regulation cost of capacitor and transformer and the operation cost of the energy storage unit and alsoconsiders the balance constrains of remaining capacity of the energy storage device. Finally

the solution isperformed by the double iterative optimization method with Cataclysmic Genetic Algorithm. The effectiveness of the proposed model is verified by the simulation and the potential of saving operation cost is fully explored on the basis of assuring safety of system voltage.
