主动配电网广义电源的优化调度策略研究
|
摘要
系统网损和节点电压偏差对主动配电网的运行安全有重要的影响。首先考虑广义电源输出功率对主动配电网的影响,将广义电源的有功功率输出作为控制变量,得到以主动配电网系统网损和节点电压偏差最小为目标函数的多目标优化模型;然后结合层次分析法和熵权法将多目标函数问题转化为单目标函数问题;接着利用混沌粒子群优化算法优化广义电源的有功功率输出量;最后分别采用改进的IEEE-33节点系统和实际主动配电系统作为算例验证了所研究模型、算法的可行性和优越性。
System power loss and voltage deviation of the active distribution network have important influence on the system operation safety. Firstly the influence of generalized power sources output on active distribution network is considered in this paper, the outputs of generalized power sources are taken as control variables to obtain the multi-objective optimization model with both minimum of the system power loss and node voltage deviation in active distribution network as the objective function. Secondly the model of multi-objective function is transformed into a single objective function by using the fusion of AHP and the entropy method,and then the active power output values of generalized power source are optimized with the chaotic particle swarm optimization algorithm. Finally the feasibility and superiority of the proposed model and algorithm are verified with both the improved IEEE-33 nodes system and a practical active distribution network system respectively as examples.
