Optimal Placement Allocation and Capacities of Storage Batteries in Future Grid

In recent years, countries have enacted CO2 reduction targets due to the progression of global warming. Therefore, in the field of electric power systems, power generation from renewable energy sources that do not emit CO2 through non-fossil fuel power generation is attracting attention. In particular, PV (Photovoltaic) is expected to see an increase in the amount of PV installed from the viewpoint that it can be introduced into ordinary households, but there is a possibility that a duck curve phenomenon will occur due to the mass introduction of PV. In order to cope with the duck curve phenomenon, PV power generation is being curbed and energy storage facilities are being installed, but PV curtailment needs to be carefully considered from the perspective of energy use. Therefore, this paper proposes Unit Commitment to determine the optimal however bar and capacity of storage batteries in the grid in 2030. This proposal enables simulations with reduced operating costs and PV suppression by determining the optimal installation bus bar and optimal capacity of storage batteries in a grid with increased renewable energy generation.
