Energy Efficiency Analyses in Polygeneration Microgrids with Renewable Sources

this article is devoted to increasing the efficiency of the use of renewable energy in polygeneration Microgrid as a combined power system for local objects with renewable sources. The development of combined power systems has led to a number of fundamental issues related to the lack of a decision-making system on the choice of structure and the ratio of capacities power generation sources at the design stage. Today's development of polygeneration Microgrids is due to the possibility of technical and informational support for the formation of the energy balance of local objects with the least capital expenditure on their implementation. Principles of optimal formation of polygeneration Microgrid structure with heterogeneous energy sources are not only in substantiating the choice of their type or capacities, and the ratio of these capacities to achieve the minimum electricity cost for the intended period of operation. The proposed method is implemented using inductive technologies of information system-analytical modeling of the energy balance of a local object polygeneration Microgrid with stochastic function renewable sources. These results can be applied in the feasibility polygeneration Microgrids studies at the predesign stage and development of systems of dynamic intellectual control of electricity consumption in networks with renewable sources. This will enable the maximum share of renewable sources in the energy balance of the Microgrid and increase its efficiency.
