Photovoltaic generation network design via a mixed integer programming model: A case study

Traditionally, electric power plant capacities are determined after specific plant locations have been selected. In recent times the focus in the design of photovoltaic (PV) systems has been shifting to ones that operate in conjunction with electric grids. In this paper, a generation expansion problem involving the choice of locations and plant capacities over a specified planning horizon (years) is tackled. The problem is formulated as a mixed integer programming model and solved using a modified embedded Benders decomposition method. The model and the algorithm developed in this paper are used to solve a renewable energy system design problem in Ghana.
