Abstract

In order to achieve economic and security operation of the grid, an economic structure of self-healing control of grid based of multi-agent system is proposed. Considering the distribution grid of micro-source configuration, load priority, healing speed and economic operation, the economic structure make distribution grid achieve maximize achieve economic operation in the case of ensure reliable operation of grid. When grid is normal operation, using the plan 1 of economic optimization optimize the grid; when grid is fault, in order to achieve fast recovery, a hierarchical optimization idea is proposed. It has not the optimization process of flow calculation as the first level optimization process, others as the second level optimization process. It can reduce the amount of calculation and carry out rapid healing, and then optimize by economic optimization plan 2.
