Title:
ENERGY STORAGE TYPE COMBINED COOLING, HEATING AND POWER DEVICE SUITABLE FOR ACTIVE POWER DISTRIBUTION NETWORK AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/127698
Kind Code:
A1
Abstract:
Disclosed are an energy storage type combined cooling, heating and power device suitable for an active power distribution network and an operation method thereof. The device consists of an electricity generating device (1), a generator (2), a waste heat recovery and absorption type heat pump (4), a high-temperature flue gas-water heat exchanger (5), a medium-temperature flue gas-water heat exchanger (6), a low-temperature flue gas-water heat exchanger (7), an energy storage electric heat pump (3), a high-temperature energy storage tank (8), a low-temperature energy storage tank (9), a cooling tower (10), various connecting valves and a circulating water pump. In the present operation method, traditional operation modes of "fixing power based on heat" and "fixing power based on cold" of a combined cooling, heating and power system are changed, so that the combined cooling, heating and power system can regulate the electricity generation and network access power, participate in the power grid load regulation and solve the problem of limited power peaking capacity caused by inter-coupling of power generation, heat supply and cold supply. Not only can the power grid adjustment capacity be improved to cope with the situation that the power peak-valley difference continuously increases, but also the system comprises a deep flue gas waste heat recovery device, so that the flue gas waste heat of the combined cooling, heating and power system can be partially or fully recovered, and the energy utilization efficiency of the system is improved.
