摘　　要：在“双碳”目标实现、新型电力系统建设和电力现货市场建设中,水电发挥着重要的灵活调节作用的同时,面临着发电收益下降的风险。水电机组可以通过出力优化来提升自身的市场化发电收益,同时为光伏等新能源提供更多消纳空间。基于浙江电力现货市场,针对水电机组出力优化和光伏发电消纳进行研究。对现货市场背景下的水电与光伏发电特点以及二者之间的关系进行分析。构建了水电机组出力的优化模型,在日发电量和日发电能力不变的前提下,优化水电日内发电策略,最大化水电机组的市场化发电收益。以浙江3次电力现货结算试运行为案例进行分析,并针对现货市场建设和新能源消纳提出建议。In the construction of new power system and electricity spot market to achieve the goals of carbon peaking and carbon neutrality,hydropower plays a crucial role in boosting the flexibility of power regulation.But it might reduce the total revenue of power generation.Hydropower generation units can increase their income of power generation by optimizing the output,and strengthen the renewable energy accommodation capacity of the power grid.Taking the spot market for electricity in Zhejiang as the example,the optimal scheduling of hydropower and the consumption of photovoltaic power are studied.The characteristics of hydropower and photovoltaic power in the power spot market and their interrelationship are analyzed.Then,based on the output optimization model of a hydropower unit,an optimal power generation strategy pursuing the maximum power generation revenue under constant power generation and daily power generation capacity is made.Three settle transactions during the trial operation of the energy spot market in Zhejiang are analyzed,and corresponding suggestions for the energy spot market construction and renewable energy accommodation are put forward.
