摘要/Abstract

摘要： 综合能源站中大量光伏接入导致公共电网联络线出现较大峰谷差，对公共电网安全运行带来不利影响。基于公共电网和能源站调度需求，提出了能够同时抑制联络线峰谷差和充分消纳光伏的综合能源站日前优化调度方法。基于负荷基值的优化调度结果提出了电网联络线功率期望值的确定方法，并在此基础上提出了考虑抑制联络线峰谷差和光伏消纳的综合能源站日前优化调度模型。该模型以综合能源站系统总费用最低为目标，根据电网联络线功率期望值设置联络线传输功率约束。算例仿真结果验证了所提方法的合理性和有效性，在保障公共电网安全运行的同时能更好地消纳光伏。

关键词: 综合能源站, 负荷基值, 联络线功率期望值, 峰谷差, 光伏消纳

Abstract: Connection of numerous photovoltaic generations in the integrated energy station has led to a big peak-valley difference in the public power grid, which has adverse effects on the safe operation of the public power grid. Based on the demand of public power grid and energy station scheduling, this paper proposes a day-ahead optimization scheduling method of integrated energy station, which can suppress the peak-valley difference of the tie line and fully absorb the photovoltaic power. Firstly, based on the optimal scheduling result of the load base value, a method is proposed to determine the tie line power expectation value. And then, a day-ahead optimization scheduling model of integrated energy station is put forward considering the tie line peak-valley difference and photovoltaic accommodation, which takes the lowest total cost as the objective and sets the tie-line transmission power constraint according to the tie-line power expectation value. The simulation results of an example have verified the feasibility and effectiveness of the proposed method, which can better absorb photovoltaic power while ensuring the safe operation of the public power grid.

Key words: integrated energy station, load base value, tie line power expectation, peak-valley difference, photovoltaic accommodation
