Abstract

The invention discloses a three-level cooperative integrative optimization method for a combined cooling heating and power system. Optimization variables are determined; optimization targets are determined; a first-level optimization target is an annual energy utilization rate, a second-level optimization target is an annual CO2 emission amount, and a third-level optimization target is an annual operating cost; a type number of to-be-selected equipment and cooling heating power loads of the combined cooling heating and power system are determined; first-level optimization is carried out, and discrete particle swarm optimization algorithm is adopted for acquiring an optimal equipment selection type; second-level optimization is carried out, and general particle swarm optimization algorithm is adopted for acquiring the optimal capacity; third-level optimization is carried out, three-level cooperative integrative optimization constraint conditions are determined; particle swarm optimization algorithm is used for optimizing optimal operating parameters; whether to meet the maximum iteration number is checked, if yes, the eighth step is returned, and if not, the fourth step is returned; and a three-level cooperative integrative optimization result of the combined cooling heating and power system is obtained. The problem of optimization of the combined cooling heating and power system which has the characteristics of multiple inputs, multiple outputs, multiple pieces of equipment, and complicated coupling can be solved.

Description

technical field [0001] The invention relates to the field of optimization design of combined cooling, heating and power systems, in particular to a three-level coordinated overall optimization method for combined cooling, heating and power systems. Background technique [0002] Energy shortage, environmental pollution and climate change are important factors restricting the sustainable development of the world economy and society. Energy and environmental issues have become major strategic issues of great concern both at home and abroad. The distributed combined cooling, heating and power system, characterized by fuel diversification, equipment miniaturization, network intelligence, and environmental friendliness, follows the principle of "proper distribution, taking what you need, matching temperature, and cascading utilization". The heat and power generation and integrated multi-generation energy system, CCHP not only realizes the cascade utilization of energy to improve t...
