Optimal design of a hybrid distributed generation system

In this paper the authors propose an optimization solution of an installation producing electricity and thermal energy viewed as an energy hub that has as input parameters four types of primary energy (solar, wind, natural gas or biomass and diesel), while hub outputs are electricity and heating needed for a consumer. Also we can take into account the fact that the hub is interconnected with the electric power system (grid) which supplies electricity directly to the hub. The energy contains a wind turbine, photovoltaic panels, storage batteries, a DC-AC converter, a Stirling engine for cogeneration, and a diesel boiler.
