| Abstract: | Introducing the concept of the Gini coefficient into the equilibrium evaluation of power line load ratio, a new index of measuring power grid balance was proposed in this paper. The iraproving scheme of power grid static safety was proposed by allocated energy storage systems （ESS） in the electric power demand side. The optimal installation locations for energy storage systems were determined by power flow tracing model, and then the optimal method of energy storage systems capacity was put forward. Then, the Matpower 30-node system was used to verify that the energy storage system in load side can improve the line load ratio index and reduce outof-limit in N - 1 fault operation condition. Results showed the described model effectiveness. |
