| 中文摘要: |
| 结合储能系统充放电切换迅速、发电调节便捷的特点，提出了兼顾储能电站的清洁能源并网电力系统风险量化与安全效益评估方案。首先，结合储能系统充放电特点，阐述了其对维持电网中长期安全生产、可靠运行以及协同促进清洁能源消纳机制的必要性。在此基础上，结合马尔科夫链蒙特卡洛仿真建立了考虑储能系统灵活充放电策略的紧急状态分析模型与风险评估模型。其次，采用经济性对比分析设计了储能电站综合效益的评价方案。最后，以修正的IEEE-6节点测试系统为例论证了所提模型与方案的有效性与先进性。 |
| 英文摘要: |
| Combined with the characteristics of rapid switching between charge and discharge and convenient power generation adjustment of energy storage system (ESS), a clean energy grid-connected power system risk quantification and security benefit evaluation plan considering energy storage power stations is proposed. Firstly, combined with the charging and discharging characteristics of ESS, the necessity of maintaining the medium and long-term safe production, reliable operation of the power grid and the cooperative promotion of clean energy consumption mechanism is explained. On this basis, combined with markov chain monte carlo (MCMC), an emergency state analysis model and a risk assessment model considering the flexible charging and discharging strategy of ESS are established. Secondly, an evaluation plan for the comprehensive benefits of the energy storage power station was designed by economic comparison analysis. Finally, the revised IEEE- 6 node test system is taken as an example to demonstrate the effectiveness and advancement of the proposed model and scheme. |
