中文摘要:

      商业建筑型微电网作为微电网的一种典型形式，得到了广泛应用，其优化运行是一门重要课题。商业建筑型微电网内配置了较大容量的可控负荷，考虑对这些负荷进行直接负荷控制，以系统综合运行成本最小为目标函数，建立商业建筑型微电网优化运行模型。引入混沌搜索对基本万有引力算法进行改进，并采用改进万有引力算法对建立的模型进行求解。最后通过一个仿真算法验证了模型的正确性和有效性，该方法能够在不降低用户舒适度的前提下，降低系统综合运行成本，且改进万有引力算法相比较传统的算法有着更优的求解性能。

英文摘要:

      Commercial building microgrid has been widely used as a typical form of microgrid, the optimal operation of which has become an important subject. The large capacity controllable load is disposed in the commercial building microgrid, the direct load control of these loads is considered, the minimum integrated operating cost is taken as the objective function, and the optimal operation model of commercial building microgrid is established.Chaos search is introduced to improve the basic gravity algorithm,and the improved gravity algorithm is used to solve the model. Finally, a simulation algorithm is used to verify the correctness and effectiveness of the proposed model. It can reduce the integrated operating cost of the system without reducing the users’comfort level, and the improved gravitational algorithm has a better performance.
