电力系统中风力发电的需求响应和灵活性提高研究

Research on demand response and flexibility improvement of wind power generation in power system

灵活性是电力系统在所有时期响应供需变化并平衡它们的能力。文章模拟了一种安全约束的机组组合(UC)结构,以便在面对风的不确定性和组件突发事件时协调供应方和需求方的运行。仿真结果表明,需求响应实施在发电侧和需求侧调度方面实现了类似的灵活性水平,传统机组可以以较低的成本访问。利用电力期望(ELNS)指数测量所述的系统可靠性。短距离消费者(SR)的网络成本降低了8%,可靠性提高了88%。SR/LR(长距离消费者)的运营成本降低了15%,负载削减值降低了90%。旨在通过规划发电机组和响应式消费者来提供必要的灵活性。最后,该模型在面对突发事件和风力发电渗透时优化了实时(RT)价格。

Flexibility is the ability of a power system to respond to changes in supply and demand and balance them at all times. This paper simulates a safety-constrained unit combination(UC)structure to coordinate supply-side and demand-side operations in the face of wind uncertainty and component contingencies. Simulation results show that demand response implementations achieve a similar level of flexibility in generation side and demand side scheduling, which can be accessed by conventional units at a lower cost. This paper uses the Power Expectation(ELNS)index to measure the system reliability described in. Short-range Consumer(SR) network costs were reduced by 8% and reliability increased by 88%. SR/Remote(LR) consumer operating costs were reduced by 15% and load reduction values were reduced by 90%. Designed to provide the necessary flexibility through planning generator sets and responsive consumers. Finally, the model optimizes real-time(RT) prices in the face of emergencies and wind power penetration.
