Economic optimization of multi-microgrid based on decentralized complex adaptive system

针对由单微电网组成多微电网系统的经济优化问题进行研究,基于体系(SoS)理论提出了分散复杂自适应体系(DCASoS)框架,建立多微电网系统双层经济优化模型。对单微电网系统层,考虑系统运行维护成本及微电网与配电网的交互成本,以微电网运行成本最低为目标建立模型;对多微电网系统层,以系统购售电成本最低为目标,考虑微电网间的能量交互建立模型。利用混合整数线性规划方法对多微电网双层经济优化模型进行求解。结果表明:所建模型实现多微电网整体运行成本最低的同时保护了微电网的隐私。

To solve the economic optimization problem of a multi-microgrid system composed of a single microgrid,a decentralized complex adaptive system framework is proposed based on the system of system(SoS)theory,and a two-layer economic optimization model of a multi-microgrid system is established.At the system layer of a single microgrid,considering the system operation and maintenance cost and the interaction cost between the microgrid and the distribution network,the model is established with the lowest operating cost of the microgrid.At the multi-microgrid system layer,aiming at the lowest cost of system power purchase and sales,the energy interaction between microgrids is considered to establish a model.The two-layer economic optimization model of multi-microgrid is solved by using the hybrid integer linear programming method.The simulation results show that the proposed model minimizes the overall operating cost of the multi-microgrid and protects the privacy of microgrids.
