通过数字仿真再现了2000年加州电力危机的动态过程,提取其时间响应曲线的稳定性特征,进行定性和定量的分析,研究电力市场的稳定性机理和可能的防御对策。文中建立了加州电力市场长期动态的近似模型,定性分析了备用容量、投资、长期合同、用户侧电价及阻塞等因素对加州电力危机的影响。
The dynamic process of the California power crisis in 2000 was reproduced by digital simulation. The stability characteristics of the time response curve were extracted and analyzed qualitatively and quantitatively to study the stability mechanism of the electricity market and the possible countermeasures. The paper establishes a long-term dynamic approximation model of California electricity market and qualitatively analyzes the impact of reserve capacity, investment, long-term contracts, customer-side electricity price and congestion on California power crisis.
