摘要: 针对多能互补微电网经济成本最优问题,提出一种计及需求侧响应的风-光-氢多能互补微电网优化配置方法. 首先,在相关功率约束和控制原则下制定运行控制策略;接着,为最大化直接消纳风光发电,引入激励型需求侧响应,利用混合整数规划优化负荷曲线;进而,建立考虑需求侧响应的优化配置模型,基于等年值成本最小的优化目标,综合考虑系统的必要约束条件,利用粒子群算法迭代寻优求解最优配置. 为验证有效性,结合某一地区的历史数据,求解优化配置方案,并开展微电网不同运营方式、自平衡率约束与建设成本影响因素下的技术经济分析. 分析结果表明:引入氢能发电系统和考虑需求侧响应后,当自平衡率为81.64%时,达到等年值成本最低为314.37万元;将自平衡率控制在合理水平,随着科技发展建设成本的降低均有助于提高微电网经济效益.

Abstract: To optimize the economic cost of multi-energy complementary microgrid, an optimal configuration method is proposed for the wind-solar-hydrogen multi-energy complementary microgrid with demand-side response. First, the operation control strategy is formulated under the relevant power constraints and control principles. Then, in order to maximize the direct consumption of wind and solar power, an incentive demand-side response is introduced, and the mixed integer programming is used to optimize the load curve. Further the optimal configuration model with the demand-side response is established: with the minimum annual cost as the optimization goal and the requisite constraints of the system, the particle swarm optimization is used to iteratively find the optimal configuration. In order to verify the model, the historical data of a certain area is utilized to solve the optimal configuration scheme, and the technical and economic analysis is carried out under different operating modes of microgrid, the self-balance rate constraint and influencing factors of construction cost. The analysis results show that by introducing the hydrogen energy power generation system and considering the demand-side response, when the self-balancing rate is 81.64%, the minimum cost to reach the equivalent annual value is 3.143 million yuan; the self-balancing rate is controlled at a reasonable level, and the cost reduction promoted by the technology advancement will help to improve the economic benefits of the microgrid.-
