基于顺序出清的常规机组惯量/一次调频辅助服务市场机制与模型OA

The research of inertia/primary frequency regulation ancillary service market mechanism is the current hot spot,in order to avoid the frequency security constraint unit commitment problem solving and the complex calculation of marginal price required by the joint clearing mode,the inertia/primary frequency regulation ancillary services market mechanism for conventional units based on the sequential clearing is proposed in this paper.After the pre-clearing of the electric energy market,the frequency safety check is carried out firstly,and then the market acquisition of inertia/primary frequency regulation ancillary services is carried out.The units which providing inertia/primary frequency regulation ancillary are identified and their settlement based on the price of inertia/frequency regulation ancillary services for marginal unit.The inertia/primary frequency regulation ancillary services costs induced by new energy generators through the pre-clearing and formal clearing process is analyzed,and a sharing methodology is proposed for this costs.The market clearing model is given,and the validity of the proposed market clearing mechanism is verified by IEEE 39-bus system case.
