Economic Dispatch of Distribution Network with Distributed Energy Storage and PV Power Stations

With the gradual increase of load in distribution network and the improvement of power supply requirements, the development of distribution network has been paid attention, and the dispatching research of distribution network has become one of the important topics. In order to ensure the stability and economy of the distribution network, the distributed energy storage systems (ESS) is considered to participate in the distribution network dispatching. With the minimum sum of the main network power purchase cost, the network active loss cost and the voltage deviation penalty cost, an economic dispatching model including the output power of photovoltaic (PV) power stations, distributed ESS and the main network is established, and the Cplex solver is called to solve this model. Finally, based on the modified IEEE 33-bus system, the simulation verifies the effectiveness and rationality of the proposed scheduling scheme.
