Multi-Objective Optimal Sizing Design of a Diesel- PV-Wind-Battery Hybrid Power System in Colombia

Abstract

This paper proposes a design of an isolated hybrid microgrid using an iterative optimization method: the branch and cut algorithm. The Colombian community of Unguía, found in the state of Chocó, has been proposed for the microgrid design. The optimization objectives are the minimization of the grid operational costs and CO2 emissions, and ensuring 80 % of load demand coverage. The elements considered in the microgrid design are: Two Diesel generators that already exists in community, a battery bank, photovoltaic panels and wind turbines. In addition a comparison between the designs obtained with the branch and cut algorithm and the software HOMER is performed for the Unguía community.
