Multi-objective Reactive Power Optimization Model Based on Ancillary Services Pricing

The power market reform puts forward higher requirements for the reactive power auxiliary service mechanism and reactive power optimization control of power system. It's an important subject to optimize the regulation and control of reactive power resources with reactive power auxiliary services pricing. Firstly, this paper adopts a three-section pricing theory based on market principle of ancillary services. Secondly cost of reactive power ancillary services is analyzed under leading phase operation and lag phase operation. Finally, multi-objective reactive power optimization model is proposed considering cost of reactive power ancillary services in electricity market. Simulations, in an actual power system of Zhejiang Province, verify the effectiveness, economy and balance of multi-objective reactive power optimization model, which meets the practical application requirements in electricity market.
