| Summary: | The structure analysis of the energy balance allows use optimal of available resources and infrastructure to maximize energy production, this is especially important for territorial communities with limited resources. The article was devoted to conduct a statistical analysis of combined energy production from wind-solar power plants and sources of thermal generation as part of a typical system of centralized electricity supply and heat for the territorial community of Smila, Cherkasy region, Ukraine. To promote the use of distributed resources, the concept of a microenergy system (MES) has been proposed and its basic structure with energy production, conversion and storage devices. Based on indeterminacy MES leaded a probability distribution model. The results showed that the MES could integrate different types of energy, such as wind, photovoltaic and gas. Multiple energy cycles were achieved through energy conversion and storage devices, and different energy needs were met. Seasonality imposed significant restrictions on the use of heat power plant on solid biofuel (HPP) and biofuel cogeneration gas-piston plant (BCP) in the summer, even without taking into account possible maneuvering modes. The level of losses increased from 19.51% till 40.83%, which leads to an increase in the cost of electricity generation. Average values of the specific cost of electricity on the monthly interval for the selected structure sources (SPP – 1.0 mW, WPP – 1.6 mW, HPP – 8.5 mW, BCP – 1.0 mW) grew in the summer from 23.63% till 53.37%. At the same time, Fe5(YL) reached the highest value in the non-heating season 0.689. The research can be used for practical purposes in the dispatching of generated electric and thermal energy |
