Optimization Methods of Renewable Integration in Power Market

Abstract

With utilization of large-scale renewable energy, renewable integration faces great challenges. In order to enhance power system’s ability to accommodate new energy and reduce electricity curtailment, an effective simulation optimization method on renewable integration is presented. Considering the constraints of transmission line capacities, an optimization model of renewable integration based on the calculation of electricity curtailment in peak regulation is set up. The measures to promote new energy accommodation in power market are proposed, including the increase of peak regulation depth, spinning reserve optimization, generation rights trade, and time-of-use (TOU) power price. Taking the actual power system of a province in 2018 as an example, the calculation and analysis of the typical scene were carried out, and effectiveness of the proposed method was proved.
