Planning of PV-ESS System for Distribution Network Considering PV Penetration

In order to tackling the energy shortage, researchers have paid close attention to distributed sustainable energy, which has great potential to replace traditional fossil fuels. On the other hand, with less pollution, the application of sustainable energy like photovoltaic (PV) and wind power can obtain ecological benefits beyond economic profits. This paper proposes a planning method of distributed PV with energy storage system (ESS), which is utilized to stabilize fluctuations of PV. In order to reflect the positive effects on ecological environment of sustainable energy, a PV penetration term is added to the objective function of the planning scheme. Numerical simulation results verify the effectiveness of the PV-ESS collaborative planning model and the rationality of the additional factor considered in configuration strategy.
