Micro-cogeneration systems combining solar PV, combined heat and power plant (CHP) and battery storage
Main Article Content
Abstract
The development of micro-grids using hybrid systems that include micro-cogeneration, is an interesting alternative to improve the efficiency in the supply of electricity and heat Thermal comfort to buildings. In addition, with these systems, the use of renewable energy sources is increased with the consequent reduction of greenhouse gases. This research examines the efficiency, and cost of hybrid systems connected to the electricity grid, comprising fuel cell combined heat and power (CHP), solar PV and battery storage. The energy demand is the electricity and heat of Facultad Regional Bahía Blanca building. This paper presents simulation results for different configurations and operations conditions of the systems, which allow determining the optimal configuration, producing 90% of electricity consumption, with a total cost for users, similar to the traditional electricity supply. With the use of CHP equipment, the purchase of electricity from the grid is reduced by 35% and 37% of the total heat required by the building is produced by cogeneration.
