已知可再生能源发电和需求预测中的不确定性水平会影响以给定的可靠性水平运行电网所需的备用数量。本文量化了随机需求和可再生能源就地调度对系统备用和可靠性的影响。考虑IEEE39节点系统的模型进行分析，包括常规发电、风力发电、需求和低频减载机构的详细动态模型。分析比较了基本情况，即可再生能源发电和需求功率是随机的，电力储备由常规发电提供，而传统随机资源的运行由于控制了局部灵活性而按照预先制定的调度计划进行调度。仿真再现了发电机停运后电网的动态行为。选择在频率减载机制下触发的偶发事件，从而为两个案例研究展示了系统运行可靠性的不同水平。仿真结果表明，传统的随机发电调度方法对于期望能量未被服务的情况有较好的分配效果，提高了系统的可靠性。

英文摘要：
Uncertainty levels in forecasting of renewable generation and demand are known to affect the amount of reserve required to operate the power grid with a given level of reliability. In this paper, we quantify the effects on the system reserve and reliability, due to the local dispatch of stochastic demand and renewable generation. The analysis is performed considering the model of the IEEE 39-bus system, with detailed dynamic models of conventional generation, wind generation, demand and an under-frequency load shedding mechanism. The analysis compares to cases: the base case, where renewable generation and demand power are stochastic and the power reserve is provided by conventional generation, against the case where the operation of traditionally stochastic resources is dispatched according to pre-established dispatch plans thanks to controlling local flexibility. Simulations reproduce the post-contingency dynamic behavior of the grid due to outages of generators. The contingencies are selected to trigger under frequency load shedding mechanisms, hence to demonstrate the different levels of system operation reliability for the two case studies. Simulation results show that dispatching traditionally stochastic generation scores better regarding to expected energy not served, producing an increase of the system reliability.
