【摘要】 随着国家电力体制的改革,电力行业发生了巨大的变化,尤其是电力市场的推进,越来越多的售电公司不断地涌现出来。在竞争性的售电市场环境中,售电公司如何通过购售电方式在避免风险的同时,增加公司利润,是售电公司提升竞争力的关键。2020年中国将在多个省份全面开展电力现货市场,对售电公司来说是机遇也是挑战。四川是电力现货市场的建设试点之一,四川售电公司呈现多、小、散的特点,市场成熟度低。本文中的售电公司针对此次国家电力市场改革,改变以往与发电企业签定中长期交易合同的购电方式,从日前市场和实时市场中购电,但仍保留与用户的中长期交易,同时售电公司拥有自己的水电机组和火电机组,为用户提供用电量,还可以在现货市场中售电。由于各个交易点现货价格是不断波动的,所以售电公司需要根据现货价格的波动不断调整水火发电机组的出力,制定不同的购售电决策。更多还原
