摘要/Abstract

摘要： 近年来，特高压工程大量建成投运，使得受端电网受电比例大幅增长。为了保证大电网运行的可靠性和调峰性，辅助服务在高受电比例的受端电网显得尤为重要。针对受端电网的辅助服务，分析探讨区外来电特性对受端电网调峰、备用的影响。在优化后调峰需求、备用需求中，将区外来电等效成三段式出力，利用多特性机组组合模型，仿真区外来电对本地机组的影响。经过仿真可以得出，相同来电容量的区外来电，火电对受端电网调峰能力影响较大、备用较小，水电由于其丰水期满发出力对低谷期备用需求影响最大，风电由于其反调峰特性对调峰影响最大，其不确定性和低谷高出力对低谷备用影响很大。

Abstract: With a large number of UHV projects being put into operation in recent years, the proportion of received electricity in the receiving-end grid has increased substantially. To improve the stability and reliability of the power grid, the ancillary service is highly important to the receiving-end grid with high-penetration received electricity. Focusing on the ancillary service, this paper discusses the influence of the characteristics of outside electricity on the peak-shaving and standby capacity demand. Based on the optimized peak-shaving and standby demand, the outside electricity is equivalent to three-segment output power, and a multi-generation combined model is used to simulate the impacts of the outside electricity on local generation sources. The simulation results show that the outside thermal power has a relatively small impacts on peak-shaving and standby demand, and the hydropower has the biggest impacts on the standby demand in valley load time because of its full-capacity generation during flood season,while the outside wind power has the biggest impacts on peak-shaving duo to its reversed peak-shaving features and very high impacts on the standby demand in valley load time due to its uncertainty and high output in valley load period.

Key words: outside electricity, receiving-end grid, ancillary service, peak shaving, standby demand
