含季节性氢储能的电力系统跨尺度全年时序生产模拟方法
Cross-time-scale Annual Chronological Production Simulation Method for Power System with Seasonal Hydrogen Energy Storage
摘要
Abstract
Hydrogen energy storage is a key means for the new power system to accommodate the large-scale renewable energy and cope with the problem of seasonal imbalance of net load.Aimed at fully assessing the role of hydrogen energy storage in accommodating renewable energy in the new power system,an annual chronological production simulation model of the power system with hydrogen energy storage is established.In order to solve the difficulty in optimal calculation due to the long time span,the large number of power equipment and the long-time coupling characteristics of hydrogen energy storage in the annual chronological production simulation model,a seasonal strategy iteration method for the annual chronological production simulation model based on the Markov decision process(MDP)is proposed.The method can adjust the annual chronological operation simulation decisions through assessing the impact of hydrogen energy storage capacity on the total operating cost for future periods,and quickly obtain an approximate optimal solution based on the value function approximation forward-looking strategy for the hydrogen energy storage capacity and its parallel updating method.Taking two modified system as cases,the effectiveness of the proposed model and its solution method is validated.关键词
