摘要: |
为了应对大规模风电接入,压缩空气储能(CAES)技术和柔性负荷主动响应技术在近年来发展迅速。以含CAES电站、可转移负荷、可中断负荷、可直接负荷控制(DLC)负荷、风电场、常规机组的电力系统为研究对象,综合考虑CAES电站和多类型柔性负荷在日前、日内、实时时间尺度下的调度特性及其在备用与调频方面的应用潜能,建立考虑源-荷-储协调互动的电力系统多时间尺度电能-备用联合调度模型。该模型以最小化电网运营商的总支出成本为优化目标,能够同时制定系统的发电计划、旋转备用购置与调用计划和自动发电控制(AGC)参与因子配置计划。基于修改版PJM-5Bus系统的仿真结果验证了所建调度模型的有效性。 |

Abstract: |
In order to cope with the integration of large-scale wind power, CAES(Compressed Air Energy Storage) technology and flexible load active response technology have been developed rapidly in recent years. Taking the power system with CAES plants, TLs(Time-shifting Loads),ILs(Interruptible Loads),DLC(Direct Load Control) loads, wind farms and conventional generators as the research object, comprehensively considering the dispatch characteristics of CAES plants and multi-type flexible loads in day-ahead, intraday and real-time scales and their application potential in reserve and frequency modulation, a multi-time scale joint dispatch model of energy and reserve is established for power system, which considers the source-load-energy storage coordination. The proposed model takes the minimum total cost of grid operators as the optimization objective, and can simultaneously set up the power generation plan, the reserve purchase and dispatch plan and the allocation plan of AGC(Automatic Generation Control) participation factors. Simulative results of the modified PJM-5Bus system verify the effectiveness of the proposed dispatch model. |
