Abstract:
As the incremental distribution network reforms, a large number of micro-energy network access systems, the formation of an urban energy internet with multiple micro-energy networks has brought huge risks to the urban energy internet dispatch. Aiming at the problem of multi-party interest interaction and regulation operation caused by multiple micro-energy networks connected to the urban energy internet, we propose an optimal scheduling strategy for an integrated energy system with multi-micro energy grids. The interaction and coordination mechanism between the micro-energy network and the main network is constructed, and the distributed modeling method is adopted to establish the economic optimization goals of each micro-energy network and the main network. Moerover, a scheduling strategy for the coordination and optimization of the multi-micro energy network and the main network is proposed. The calculation example shows that the dispatch strategy proposed in this paper guarantees the privacy of the micro-energy network information, improves the initiative of the micro-energy network, improves the level of interconnection and mutual benefit between the power and natural gas systems, and reduces the peak load of the urban energy internet. The valley gap has achieved mutual benefit and win-win results for all micro-energy networks and integrated energy operators.
