Research on Deployment Scheme of Aggregation Control Gateway for Hybrid Network of Virtual Power Plant

Acquisition Sensing Infrastructure (ASI) is the main technology of Virtual Power Plant. It can send commands to Smart Meters to establish two-way communication. The meters data is aggregated at the Aggregation Control Gateway (ACG) and then send to the Virtual Power Plant center server. In complex and changeable distribution network environment,a data aggregation deployment scheme based on wired-wireless hybrid network is proposed to reduce the cost of ACG placement. This scheme presents the optimization problem of finding the optimal location of the aggregation nodes and divide the placement nodes into available nodes and potential nodes. This kind of hybrid network facilitates communication between the user and the microgrid in its own interior, reducing the latency of energy services and the overhead of data aggregation. Besides, the improved K-means algorithm is proposed to decrease the algorithm complexity. The data results show that the virtual power plant network infrastructure and ACG deployment model based on wired/wireless hybrid network can reduce the cost and the density of ACG.
