摘要:

动态环境经济调度(Dynamic environment economic dispatch, DEED)是电力系统中常见的高纬度、非线性和强耦合的多目标优化问题,以风电为代表的可再生能源大规模并网后使得电力系统动态调度面临一定挑战。在传统的DEED模型中加入应对风电随机性的旋转储备约束,构建了以燃料成本和污染排放为目标,考虑传统发电机阀点效应、网络损耗、爬坡速率和旋转备用要求的DEED模型。基于模型特点,提出一种新型的多目标飞蛾扑火算法(Multi-objective moth-flame optimization, MOMFO),并针对模型复杂约束采用一种动态松弛处理机制。最后以10机测试系统的不同调度方案为例验证了MOMFO在解决此类问题的可行性与有效性。

Abstract:

DEED is a common multi-objective optimization problem with high latitude, non-linearity and strong coupling in power system. In order to cope with the impact of wind farm random fluctuation on power system dynamic scheduling, the spinning reserve constraint considering wind farm randomness is added into the traditional DEED model. A DEED model considering both fuel cost and pollution emission target, valve point effect of conventional generators, network loss, spinning reserve requirement and climbing rate is constructed. According to the characteristics of DEED model, a new multi-objective moth-flame optimization (MOMFO) is proposed. Furthermore, a dynamic relaxation constraint processing mechanism for model complex constraints is adopted. Finally, the feasibility and validity of MOMFO in solving this kind of problems are verified by taking different scheduling schemes of 10-machine test system as examples.

Key words: Large-scale wind power, dynamic environment economic dispatch, moth-flame optimization, multi-objective optimization, dynamic relaxation
