Economic analysis for management of distributed generation systems on electrical networks

This paper presents a study, using the software HOMER, for the adequate electrical and economic dispatch analysis of distributed generation systems with renewable energy resources. In this way, sensitive analyses can be worked out to simulate the system performance and to examine the attractiveness of the different power dispatch according to the management needs. The general logic is always illustrated with a case-study based on the power flow of a Brazilian university. For this purpose, there are connected three different types of electricity generation to the university´s grid, namely: wind turbines, photovoltaic panels, and fuel cells fuelled by hydrogen gas.
