可信容量在衡量间歇性电源接入电力系统的价值中具有重要意义。目前关于可信容量的研究仅限于单种电源，对不同类型间歇电源的联合发电系统可信容量缺乏研究。建立了包含风电、光伏发电的联合出力概率模型，考虑储能装置的运行特性，提出一种风光储联合发电系统的可信容量计算方法。采用基于序贯蒙特卡洛的评估框架，实现了计及风电机组、光伏发电机组2种间歇性电源的随机生产模拟，在所提储能控制策略的基础上，评估了储能容量配比、风光装机容量配比对联合发电系统可信容量的影响以及风光联合发电时的互补效益。采用加入了风电和光伏发电后的 RTS-79可靠性算例测试了评估算法的有效性，结果表明该方法可以用于评估含风光储联合发电系统的电源容量规划方案中。

The capacity credit is significant in weighing the value of integrating intermittent power sources with power grid. At present the research on capacity credit is restricted to the single kind of power resource and the research on the capacity credit of power generation system integrated with different types of intermittent power sources is almost absent. A probabilistic power output model for the power generation system integrated with wind farm and photovoltaic (PV) system is established, and considering the operation characteristics of energy storage system, a calculation method for the capacity credit of the power generation system integrated with wind farm, energy storage system and PV system is proposed. Using the sequential Monte Carlo simulation based assessing frame, the probabilistic production simulation for power generation system composed of two types of intermittent power resources, namely wind power generation units and PV arrays, is implemented;based on the proposed control strategy of energy storage system, the impacts of the proportion of the capacity of energy storage system and the proportional ratio between install capacity of wind power generators and that of PV arrays on capacity credit of integrated generation system as well as the complementary benefit of combined power generation integrating with wind power generation and PV generation are assessed. The IEEE RTS79, to which the wind power generation and PV generation are added, is used to test the validity of the proposed assessment algorithm, and testing results show that the proposed method can be applied to the assessment of power source planning scheme containing combined generation system integrating with wind farm, energy storage system and PV system.
