Problems solved by technology

At present, the evaluation of combined cooling, heating and power system is mostly aimed at its economy, and there is no evaluation of the comprehensive benefits of the combined cooling, heating and power system. At the same time, there is a lack of evaluation methods for the comprehensive benefits of the combined cooling, heating and power system. Little consideration is given to the environmental impact of combined cooling, heating, power, and trigeneration systems
Therefore, it often leads to the cogeneration system not always running in the best state

Abstract

The invention discloses a comprehensive benefit evaluation method of a combined cooling heating and power (CCHP) system. The method is characterized in that a comprehensive benefit evaluation system including an economic indicator, an environmental indicator and an energy efficiency indicator is established, and the indicators are integrated and quantified through utilizing a weighting method to evaluate the comprehensive benefits of the combined cooling heating and power system. The method is advantaged in that the combined cooling heating and power system is comprehensively evaluated, and economic benefits, the environment impact and the energy efficiency indicator of the combined cooling heating and power system in actual applications can be effectively improved.

Description

technical field [0001] The invention relates to a method for comprehensive benefit evaluation of a combined cooling, heating and power supply system, which is applicable to the comprehensive benefit assessment of the combined cooling, heating and power supply system under different scenarios, different operation modes, and different control strategies. Background technique [0002] With the increasing energy crisis and environmental pollution, people's technological innovation of power equipment has begun to shift from pursuing high efficiency and low energy consumption of individual equipment to focusing on energy cascades, efficient comprehensive utilization and environmental protection. Combined cooling, heating and power supply is a multi-combined total energy system based on the concept of energy cascade utilization, which integrates the subsystems of refrigeration, heating (heating and hot water supply) and power generation. However, there is a coupling relationship be...
