摘要:

针对电力市场环境下多能协调优化运行系统中风电、光伏出力不确定性问题,提出了一种计及公平性的风光储多源合作博弈鲁棒优化调度模型。构建了以风力发电、光伏发电、抽水蓄能电站和光热电站为发电单元的多源发电系统,在发电系统内部建立计及公平性的合作博弈优化调度模型;在合作博弈模型的基础上,结合鲁棒优化理论,引入鲁棒因子,将含有不确定性的约束条件转化为确定性约束,实现模型的鲁棒化。以甘肃某地区电网为例进行算例分析,分析结果表明:模型具有灵活性,能适应不同稳定性要求下的运行需求,系统运营者可通过调整鲁棒系数来调节对系统随机性的容忍度;相比于非合作博弈情景下的收益,采用合作博弈时系统的总体收益高,能够充分发挥合作博弈的优势,促进新能源联合系统的可靠运行。

Abstract:

In view of the uncertainty of wind and photovoltaic outputs in multi-energy coordinated optimal operation system under electricity market environment, a robust optimal scheduling model of wind-PV-storage multi-energy cooperative game considering fairness is proposed. Firstly, a multi-energy power system integrated with wind power generators, photovoltaic power generators, pumped storage power stations and photovoltaic thermal power stations (CSPs) is constructed, then a cooperative game optimization scheduling model considering fairness for this power system is established. On the basis of the cooperative game model and robust optimization theory, the model gets robust by introducing robust factors to transform the uncertain constraints into deterministic constraints. The model is analyzed and verified by a power grid in Gansu Province. The analysis shows that the model is flexible and can meet the operation requirements under different stability requirements. The system operator can adjust the inclusiveness of the randomness of the system by adjusting the robust coefficient. Compared with the benefit under non-cooperative game scenario, the overall benefit of the system adopting cooperative game is higher, since giving full play to the advantages of cooperative game can promote the reliable operation of new energy integrated system.

Key words: multi-energy power system, renewable energy, pumped storage power station, CSP, game theory, robust optimal scheduling, scheduling fairness, carbon neutrality
