Abstract
High penetration of distributed photovoltaic(PV)systems into the power distribution networks has caused voltage violations,constraining the PV absorption capacity.This paper first analyzes the impact of distributed PV integra-tion on the voltage distribution in the network.Subsequently,it works out a time-of-use electricity pricing optimization model and a distributed photovoltaic acceptance optimization model to enhance the PV absorption capacity of the distri-bution network.The time-of-use pricing optimization model is a multi-objective framework aimed at increasing consumer power usage while reducing electricity costs,with constraints including consumer power demand and pricing.Based on the results of the time-of-use pricing model,the distributed photovoltaic acceptance optimization model is proposed to maximize the PV absorption in the distribution network.This model involves constraints derived from the time-of-use pricing model,such as network load and line flow limitations.A case study on a real-world distribution network system is presented,and the results demonstrate that the application of these two optimization models effectively enhances the PV absorption capacity.关键词
