Proposing a distributed generation curtailment optimization model to minimize total power losses of distribution network

In recent years, Distributed Generation has grown explosively, especially solar power, and the impact of the COVID-19 which has lowed the load, caused the unbalance between electricity supply and demand. In order to solve this problem, the Ministry of Industry and Trade has taken measures to direct Vietnam Electricity to manually reduce this energy source. At present, the member Electricity companies only curtail equally for all investors, this curtailment model is not optimal in terms of power losses. In this study, an optimization model is developed to help power companies obtain an optimal curtailment result in terms of minimizing the power losses on the distributed grid when needed. The proposed model is validated with the real data provided by Thue Thien Hue Power company and commercial software.
