| 摘要: |
| 针对新能源机组出力的随机性与波动性导致其消纳难的问题，利用一种基于等效电量函数法的随机生产模拟算法辅助新能源与常规能源的协调规划。首先，以多状态机组为基础，引入分段模拟体现新能源的时序性，克服传统等效电量函数法丢失时序信息的缺点。然后，在系统可靠性指标(LOLP和EENS)的基础上，提出两个描述系统调峰性能的指标——调峰容量不足概率与调峰电量不足期望值。最后，采用IEEE的RTS-86测试系统验证算法的准确性和可行性，以及探究风光能源接入对系统可靠性和调峰性能的影响。 |

| Abstract: |
| The randomness and volatility of new energy cause difficulties in grid-connection and consumption. Based on the Equivalent Energy Function Method, a probabilistic production simulation algorithm is proposed, which helps to coordinate planning of new energy and conventional energy. Firstly, based on the multi-state model, segmented simulation is proposed to embody the timeliness of new energy, and the traditional Equivalent Energy Function Method’s shortcoming of losing timing information is overcome. Secondly, based on the system reliability indices (LOLP and EENS), two indices describing the system’s regulation performance are proposed, which includes Loss of Regulating Capacity Probability (LORCP) and Expected Regulating Energy Not Supplied (ERENS). Finally, the IEEE RTS-86 is applied to verify the accuracy and feasibility of the proposed algorithm and study the impact of wind and solar on system reliability and regulation.
