中文摘要:

高比例新能源并网电力系统中，系统惯量不足越发严重，频率稳定受到严重威胁。已有的机组优化调度模型中，仅考虑了电源侧的调频，尚未考虑负荷侧的调频能力。文章提出了一种应用于高比例新能源并网电力系统的双层优化调度模型。内层综合考虑电源侧新能源机组、同步发电机组和负荷侧异步电机的频率响应能力，求解满足频率安全条件下的新能源机组虚拟惯量和调频容量需求。外层在机组优化调度的基础上量化新能源机组的调频成本，以实现满足频率安全条件下的最优调度。以IEEE10机39节点为算例原始模型，通过对比分析，证明该模型能一定程度降低系统的运行成本以及满足频率安全条件下的惯量和调频容量需求。

英文摘要:

In power systems with a high proportion of renewable energy generation (REGs) connected to the power grid, the problem of system inertia shortage, which significantly threatens the frequency stability of the system, is becoming increasingly serious. However, the previous unit commitment (UC) optimized dispatching model only focuses on the frequency regulation of the power source, whereas the frequency regulation ability of the load side is not considered. To fill this gap, this study constructs a bi-level optimized dispatching model applied to power systems with high proportion of REGs penetration. The inner layer synthetically considers the frequency response capabilities of the power-source REGs, synchronous generators, and load-side induction motors. This layer aims to solve the virtual inertia and frequency regulation capacity requirements of the REGs under the premise of frequency security. Based on the UC, the outer layer quantifies the frequency regulation cost of REGs to achieve optimal UC decisions under the prerequisite of ensuring frequency security. Taking the IEEE 39-bus power system as the original model, this study provides empirical evidence that the proposed bi-level optimization model can reduce the operating cost of the system to a certain extent and satisfy the demand for inertia and frequency regulation capacity under the precondition of security.
