| Abstract: | In this paper,several effective means of reducing the active power loss and a method to evaluate the energy-saving potential are proposed for regional main power grid.The investigation mainly involves the optimal replacement of heavy transmission lines,the economic operation of the main transformer,the load distribution optimization,the optimal dispatching of power plants and the reactive power optimization.Then,a general idea of energy-saving planning is presented,and a case study is performed on an actual regional main power grid to evaluate the energy-saving potential according to a series of flow and reactive power optimization calculation.Finally,a relevant energy-saving planning is worked out and its energy-saving effectiveness is verified. |
