Multi-objective planning of multi-type distributed generation considering timing characteristics and environmental benefits

通过分析多种类型分布式电源并网所带来的投资及收益情况,提出了一种多类型分布式电源的选址定容规划方法。该方法考虑了负荷与分布式电源出力的时序特性以及分布式电源的环境效益,在对日负荷序列和分布式电源日出力序列进行归类的基础上求取了典型日负荷序列和单位容量分布式电源的典型日出力序列。以分布式电源的位置、容量和类型为优化变量建立了数学规划模型并采用改进自适应遗传算法对模型进行求解。实际算例验证了所提出的方法及模型的可行性和有效性。

A planning method for locating and sizing of multi-type distributed generation is proposed based on the analysis of the investment and income brought by many types of grid-connected distributed generation. This method analyzes the timing characteristics of load and distributed generation output and the environmental benefits of distributed generation. The typical daily load sequence and the typical daily output sequence of distributed generation per capacity are calculated on the basis of the classification of daily load sequence and daily output sequence of distributed generation. The mathematical planning model with the location, capacity and type of distributed generation as the optimization variables is established and the improved adaptive genetic algorithm is used to solve the model. Finally, a practical example is employed to verify the feasibility and effectiveness of the proposed method and model.
