摘要

为提高光热-光伏运营主体的收益与消纳能力,考虑吸热、储换热、发电、熔盐电加热等系统模块的启停及动态切换条件,建立联合电站多时间尺度动态优化调度模型,以响应调峰需求并最大化联合电站收益;模型耦合电力系统日前-日内滚动经济调度,以优化出力结果作为申报出力曲线,构建以最小化电力系统综合运行成本为目标的优化调度模型;最后以西北某地区电力系统的实测数据为算例进行分析。算例分析表明：面向调峰的该策略相较于传统调度策略和收益最大化策略分别提高电站总收益13.48%和6.67%,电力系统的弃风弃光率分别减少1.39%和0.5%。

Abstract

Concentrating solar power （CSP） generation, which encompasses both energy storage and power generation capabilities, has emerged as a grid-friendly renewable energy technology and has become a standard configuration within wind and solar power bases. To further enhance the profitability and consumption of CSP-PV operators, this paper primarily focuses on the impact of the startup and dynamic switching conditions of subsystems such as receiver, heat storage, power generation, and electric heater using molten salt on the performance of CSP-PV hybrid power plants. Aiming to optimize the income generated by the hybrid plant, a multi-time-scale dynamic optimization output model is established. This model also incorporates the power system’s optimal scheduling for day-ahead and intra-day, and the optimized output is then used as the declared power output curve. An optimal scheduling model, aimed at reducing the comprehensive operating costs of the power system, has been established. Finally, the measured data of a power system in a certain region of Northwest China is taken as an example for analysis. The case analysis shows that compared to traditional scheduling strategies and profit-maximization strategies, this peak regulation-oriented strategy increases the total power plant revenue by 13.48% and 6.67% respectively, while reducing the curtailment rates of wind and solar power in the power system by 1.39% and 0.5% respectively.
