Optimal Dispatch of Regional Integrated Energy System Group including Power to Gas Based on Energy Hub

Different renewable energy resources and demands between parks lead to waste of frequent interactions the regional distribution grid larger grid. Hence, an optimal dispatching scheme integrated system group (RIESG), which combines power-to-gas (P2G) inter-park electric mutual aid, is proposed in this paper solve problem. Firstly, for park (PIES) with various structures, coupling matrix used describe input-output relationship form multiple sources energy-hub (EH), linearizes complex multi-energy coupled more conducive solution model. Secondly, electrical improved by adding P2G enhance system’s ability consume energy. Moreover, installation cost introduced comprehensively consider impact economic efficiency on system. Finally, minimize network loss flow, model RIESG conversion constructed through aid among parks. The simulation shows that compared independent operation each park’s (IES), strategy achieves benefit groups, reduces dependency large power grid, effectively improves economy groups. In condition, consumption rate reaches 99.59%, utilization increases 94.28%, total reduced 34.83%.
