Gas power is the key peak-shaving and frequency-modulation power supply to solve the randomness,volatility,and intermittence of new energy output of wind and solar energy and the main power supply to support the construction of the integrated energy base of wind & solar energy and UHV power transmission channel.Clean,low-carbon,and efficient natural gas will play an irreplaceable role in the new energy system.The gas consumption characteristics of integrated energy bases supported by gas power are quite different from those of traditional industries.The characteristics of"winter and summer bimodal"seasonal fluctuations,daily irregular fluctuations,and intraday hourly regular fluctuations of gas consumption in integrated energy bases have higher requirements for gas storage and peak shaving.This paper systematically demonstrates the technical and economic comparison of such peak shaving methods as underground gas storage,flexible peak shaving of gas fields,LNG storage tanks,ground high-pressure spherical tanks,and high-pressure pipelines,explores the multi-system level and multi-time scale gas storage and peak shaving methods by combining with the gas consumption characteristics of integrated energy bases,and proposes the suggestions from the perspectives of policy support,demonstration application,and technical research.
