摘要
发电上网分时电价与当时的发电燃料边际成本及供电风险密切相关,随机生产模拟计算可以给出系统的最优发电方式、燃料费用、边际发电成本及系统可靠性指标。在随机生产模拟计算的基础上,提出了3种既考虑电能成本又考虑风险成本(可靠性成本)的分时电价制定方案,并以某实际系统为例计算出典型日运行方式下每种方案的分时电价,同时统计出该运行方式下的峰、腰、谷分时电价比,为电网实现分时电价提供了参考和依据。
Power system hourly price is closely related to power energy marginal cost and risk cost. By stochastic production simulation, the optimal generation scheduler, fuel cost, system marginal cost and reliability indices can be obtained. Based on the stochastic production simulation results, three electricity pricing models and the principle of partition of the peak-valley electricity price are discussed. At last, a practical power system is utilized to obtain the different power system hourly prices and the ratio of peak-waist-valley price, which can provide references for the establishment of the actual power price.
