The novel cooling, heating and power combined supply system comprises a distributed cooling, heating and power combined supply system, an electricity price peak and valley module and an energy storage module, and the energy storage module comprises a cold load storage module and a heat load storage module; and the distributed cooling, heating and power combined supply system is provided with multiple layers of waste heat recovery modules, and after waste heat recovery is conducted through the multiple layers of waste heat recovery modules, the output ends of the multiple layers of waste heat recovery modules are connected with the cold load storage module and the heat load storage module. A power module connected with the power output end of each generator is arranged in the electricity price peak and valley module, an electricity price peak and valley strategy is set in the power module, the power module performs quick charging when the electricity price is valley, and the power module performs discharging when the electricity price is peak. The waste heat recovery output optimization method is based on an improved whale optimization algorithm, optimal output processing is carried out on a heat exchanger waste heat recovery module, the waste heat recovery efficiency is improved, and the overall energy utilization rate of the system is increased.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a novel combined cooling, heating and power supply system and a waste heat recovery output optimization method. Background technique [0002] Nowadays, under the background of the world's energy shortage, the efficient use of energy has become a research focus in various countries and regions. [0003] The current power supply system mainly adopts centralized power supply, while distributed power supply is gradually adopted in western countries. And for some key places, such as chemical plants, hospitals, etc., stable power supply is required. At the same time, according to seasonal changes, these places have different demands for cooling load and heating load. Simply relying on the electricity transmitted by the grid to accomplish these goals not only increases the economic burden, but also inevitably causes corresponding environmental pollution. Therefore, a small...
