摘要:

构建以新能源为主体的新型电力系统是“双碳”目标的枢纽平台,但新能源发电的不稳定性给电力系统带来了调峰挑战和灵活性缺失等难题。为有效平衡系统的经济性与安全性,首先,引入改进最差条件风险价值(WCVaR)来量化评估新能源出力不确定性带来的潜在风险;其次,引入激励策略平衡用电负荷并对火电机组进行调峰-碳捕集优化升级,提升调峰能力及新能源消纳水平,缓解火电机组深度调峰带来的过度碳排放问题;再次,建立以系统运营成本与运行风险综合最优为目标的低碳经济调度模型;最后,通过仿真验证了所提模型的有效性。

Abstract:

Building a new power system with new energy as the main body is the hub platform for the “dual carbon” goal,but the instability of new energy generation brings challenges such as peak shaving and lack of flexibility to the power system.To effectively balance the economy and safety of the system,the following steps are taken.Firstly,the improved Worst Condition Value at Risk (WCVaR) is introduced to quantitatively evaluate the potential risks brought by the uncertainty of new energy output.Secondly,an incentive strategy is introduced to balance the electricity load and optimize and upgrade the peak shaving carbon capture of thermal power units,enhancing peak shaving capacity and new energy consumption level,and alleviating the excessive carbon emissions caused by deep peak shaving of thermal power units.Thirdly,a low-carbon economic dispatch model is established with the goal of achieving comprehensive optimization of system operation costs and operation risks.Finally,the effectiveness of the proposed model is verified through experimental simulations.

Key words: new power system, deep peaking, improved WCVaR, low-carbon economic dispatching
