Analysis Of Operation Cost Share Of Distribution Network

The taking off of China's economic makes the load of grid electricity growing up, which makes China's electric power grid structure increasingly complex.In this case,the power distribution has been become more random,which intensively challenges the existing technologies of economic dispatch of power system.In this paper,with the theoretical power distribution grid and the cost of the basic principle of flow conservation,it is built theoretical basis of the power grid node and the slip cost flow analysis and calculation.By this theory,it is given reactive adjusted physical parameters change grid factor,given adjust reactive components(devices) of the economic share of the analytical expression and got distribution network operating costs of the cost flow factors and changes in factor allocation.Finally,through the example of IEEE-39 bus system,it is verified that the method provides a reference strategy and a reference means to adjust of reactive scheduling of distribution network,which has great significance for economic dispatch of distribution network.It is provided the theoretical basis for running cost control of economic dispatch of distribution network.
