Energy Efficiency of the Heat and Power Complex for Highly Efficient Use of the Secondary and Renewable Energy Resources

Abstract

The article describes a heat and power complex utilizing internal sources of consumer heat, as well as using renewable energy sources. The power complex also includes heat accumulators, cold accumulators and a cascade heat pump plant. This heat pump plant has a high conversion factor of electrical energy due to optimization of heat flows. In this article, a method for determining the energy efficiency of the heat-energy complex under consideration is disclosed.

Logistics and principles of use of solid and liquid household waste, as relevant energy resource

“…Now the subject of power complexes quite actively progresses in scientific and technical literature as complex generation of energy from several sources gives high reliability of receipt of required amount of energy [1][2][3][4][5][6].…”

Multi-energy conversion based on game theory in the industrial interconnection

“…Among different techniques for energy management, the multi-energy conversion system (MCS) is one of the effective approaches that can weaken the dependence on fossil energy. This system operates with a conversion device (such as heat pumps [ 4 ], gas boilers [ 5 ], and gas-fired combined heat and power plants(CHP) [ 6 ] to convert excess generated energy effectively into other forms of energy, thereby, improving the utilization of energy resources [ 7 ]). In addition, advanced metering infrastructure and intelligent instruments in the system enable energy suppliers to provide customers with historical energy consumption records and real-time price data [ 8 ], effectively improving the efficiency of energy generating and monitoring [ 9 , 10 ].…”
