A Study on Voltage Management Considering Fairness of Consumers in Distribution System with Photovoltaic Generations

Abstract

In this paper, we focus on the voltage management problem in a distribution network in which a large amount of photovoltaic generations (PV) are penetrated. The proposed system employs a novel voltage control system utilizing controllable loads of consumers which are controlled based on an index to quantify a fairness between consumers. The main contributions of the paper are that (i) the index to quantify the fairness between consumers is firstly introduced, (ii) a novel voltage control system with low-cost communication infrastructure is proposed, and (iii) a mathematical model which efficiently optimizes a large amount of controllable loads by a commercial solver is proposed in the context of a implementation of the proposed method into a real world system. We verified the effectiveness of the proposed method by a computational experiment in which there are many consumers, low-cost communication network, and low-cost optimization manager.
