Abstract
The percentage of heat pumps used in thermal power plants (TPPs) in the fuel and energy balance is extremely low in in most countries. One of the reasons for this is the lack of a systematic approach to selecting and justifying the circuit solutions and equipment capacity. This article aims to develop a new method of calculating the maximum capacity of heat pumps. The method proposed in the article has elements of marginal analysis. It takes into account the limitation of heat pump capacity by break-even operation at electric power market (compensation of fuel expenses, connected with electric power production). In this case, the heat pump’s maximum allowable capacity depends on the electric capacity of TPP, electricity consumption for own needs, specific consumption of conditional fuel for electricity production, a ratio of prices for energy resources, and a conversion factor of heat pump. For TPP based on combined cycle gas turbine (CCGT) CCGT-450 with prices at the Russian energy resources markets at the level of 2019, when operating with the maximum heat load, the allowable heat pump capacity will be about 50 MW, and when operating with the minimum heat load—about 200 MW.

The method is based on limiting the capacity of a heat pump under the condition of break-even operation on the electricity market
Summary
Global environmental problems and the continuous increase in energy consumption worldwide require technologies that integrate renewable and secondary energy resources into the energy balance [1]. Active research work on the analysis and justification of lowpotential heat (LPH) applications in existing heating systems by using heat pumps (HP). Several studies are devoted to the analysis of environmental and market aspects of HP integration in heat supply systems of different countries Researchers in articles look at various options of HP application in systems of district heating based on the conditions of energy markets in Denmark [7], Sweden [8], Norway [9], and China [10]. There is significant research done on heat pump technology applications aimed at improving the sustainability of energy supply in Spain [11], China [12], Norway [9], and Germany [13]
