Energy Management of a Small Spare Energy Subsystem Far away from Large Integrated Energy System

In recent years, asynchronous communication energy management technology of traditional integrated energy system has been developed and improved. However, there is no study for a small subsystem of Integrated energy system in sparse places (SIESP). The demand of SIESP is exceedingly different from that of traditional IES. On the one hand, Due to the fact that SIESP is small and the energy in SIESP is a little, so the economic performance of SIESP isn't as significant as IES. On the other hand, Due to the long distances between SIESP and other energy systems, its energy transfer and asynchronous communication costs are very high. For these problem, we designed a sparse agent in asynchronous communication algorithm (SAACA) for SIESP. The sparse agent is the SIESP. Compared with traditional methods designed for all types of IES, This algorithm is more suitable for SIESP due to the reduced overhead of asynchronous communication in SIESP. Simulation results and theoretical identifications have strictly proved the effectiveness of the method.
