Beschreibung
Zusammenfassung:	The invention provides a gas-electric coupling liquefied natural gas energy storage peak regulation system and method based on natural gas, and the system comprises a natural gas liquefaction device, a liquefied natural gas storage tank, an internal combustion engine power generation device, a power cycle power generation device and a control device. The control device is in signal connection with the natural gas liquefaction device, the power cycle power generation device and the internal combustion engine power generation device. According to the system, valley-time electricity can be used for preparing LNG, the power cycle power generation device is used for preparing electricity and releasing part of natural gas at the same time in the electricity utilization peak period, the power cycle power generation device is used for producing electricity through LNG cold energy and internal combustion engine waste gas heat energy, electric energy can be effectively recycled, and the comprehensive capacity of electr
