| 摘要: |
| 为了减轻微电网接入对配网带来的影响，同时提高微电网参与配网优化调度的积极性，提出一种基于动态奖惩电价的含多微电网的配网分层协调优化模型及其优化方法。该模型以10 kV馈线处负荷曲线削峰填谷为目标，给出各微电网的参考计划交换功率曲线，各微电网再以各自综合发电成本最小为目标、日前调度交换功率为约束进行二次优化，与配网下发计划交换功率曲线进行匹配，根据匹配程度调整动态奖惩电价。引入一种改进的细菌群体趋药性算法，通过速度和感知范围的自适应调整，使算法的全局和局部搜索能力得到平衡。通过拉丁超立方抽样产生分布更为广阔的初代细菌，从而减少算法陷入局部最优的可能性。以接入微电网的IEEE 69节点配网作为算例，验证了所提模型和算法的有效性。 |

| Abstract: |
| In order to alleviate the impact of integrated microgrid on distribution network and increase the enthusiasm of microgird participating in the optimal dispatch of distribution network，a layered and coor-dinated optimization model based on the dynamic award and penalty price is proposed with the optimization method for the distribution network integrated with multiple microgrids. At the network layer，it takes the load shifting of 10 kV feeder as its objective to obtain a power-exchange schedule reference for each micro-grid，and at the microgrid layer，it takes the minimum total cost as its objective and the day-ahead power-exchange dispatch as its constraint，which is compared with the obtained power-exchange schedule reference to determine the matching degree for adjusting the dynamic award and penalty price. An improved bacterial colony chemotaxis algorithm is applied to balance the global and local search abilities by adaptively adjus-ting the velocity and perception range. The Latin hypercube sampling method is adopted to generate the original bacteria with wider distribution for reducing the possibility of local optimum. IEEE 69-bus distri-bution network integrated with microgrids is taken as an example and the results of case study verify the effectiveness of the proposed model and algorithm. |
