Abstract: Related to the field of charging infrastructure optimization, a method for online coordinated optimization scheduling of truck mobile charging stations. A two-stage framework is proposed: (1) offline training stage, where a multi-period optimization decision model for TMCSs is constructed, and a look-ahead rolling horizon-value function approximation (LRH-VFA) algorithm is then developed to iteratively learn from historical EV charging data, considering the impact of current-period decisions on future profit; and (2) online scheduling stage, where TMCS scheduling decisions are dynamically updated based on the approximate value function obtained from offline training, along with short-term forecasts and real-time information. The method effectively accounts for the impact of uncertain EV charging demand on TMCS scheduling, dynamically adjusting decisions based on real-time updates.

Abstract: The invention pertains to optimal scheduling and trading technology for microgrid systems, specifically focusing on a real-time peer-to-peer energy trading method involving time-varying virtual energy storage. This method predicts environmental information within a specified time domain and incorporates historical transaction data into virtual energy storage modeling and real-time energy trading. During the supply and demand energy extraction phase, it quantitatively extracts supply and demand energy and the marginal cost for trading using an autonomous energy management model for prosumers. In the transaction price optimization phase, it optimizes the transaction price based on historical data to maximize prosumers' income. The distributed transaction decision optimization method, utilizing a continuous double auction, enhances transaction matching decisions to maximize prosumers' income and accommodate multi-transaction preference levels.
