摘要

为有效协调联合市场运营方的经济成本与机组方的调频市场收益,提出一种联合市场环境下多源参与的双层优化竞价模型。市场运营方通过上层模型制定发电计划,并确定各机组在调频市场中的调频容量中标值,其优化目标为减少联合市场综合运营成本;基于上层模型运行结果,机组方通过下层模型调整其调频市场报价策略,其优化目标为提高被优化机组方的调频市场收益,在经济性优化的基础上保证系统的调频性能。通过算例验证可知,当下层模型主体为火电机组时,双层优化模型使得火电机组方的一次调频收益在联合市场综合成本趋于稳定的基础上有所提高;当下层模型主体为新能源机组时,双层优化竞价模型使得新能源机组方的一次调频收益较优化前有所提高,联合市场综合成本有所下降,利用经济性优化提高新能源机组调频参与积极性的同时,系统获得了更优的调频性能,结果显示此情况下的系统综合调频性能量化均值较优化前有所提高。

Abstract

In order to coordinate the economic cost of the joint market operator and the frequency modulation auxiliary service market benefit of the unit, a bi-level optimal bidding model with multi-source participation in the joint market is proposed. The market operator makes power generation plan through the upper level model, and determines the target value of the frequency modulation capacity of each unit in the frequency control auxiliary service （FCAS） market. Its optimization objective is to reduce the comprehensive operating cost in the joint market. Based on the operation results of the upper model, the unit adjusts its FCAS market quotation strategy through the lower model. Its optimization objective is to improve the frequency modulation market income of the optimized unit and ensure the frequency modulation performance of the system on the basis of economic optimization. The results show that when the main optimal body of the lower model is the summation of thermal power units, the bi-level optimization model makes the primary frequency modulation revenue of the thermal power units improve on the basis of the comprehensive cost of the combined market tends to be stable. When the main optimal body of the lower model is the summation of new energy units, the bi-level optimal bidding model improves the primary frequency modulation income of the new energy unit, and reduces the joint market cost. While improving the participation enthusiasm of the new energy units in frequency modulation through economic optimization, the system obtains better frequency modulation performance. The results show that the quantized mean of the integrated frequency modulation performance of the system is improved compared with that before optimization.
