Abstract:In order to solve the difficulty of collecting high proportion of distributed photovoltaic (PV) data in distribution station, a virtual collection method for distributed PV data based on optimal deep belief network is proposed. The optimal deep belief network consists of two parts, namely basic deep belief network and adaptive firefly algorith, in which the adaptive firefly algorithm is used to estimate the output weight matrix of deep belief networks. Firstly, the proposed virtual collection method for distributed PV data can realize the virtual data acquisition of all distributed PV equipment in the same PV power station under the condition that only one distributed PV equipment has a complete data acquisition device. And then, the proposed virtual collection method for distributed PV data is verified with 100 distributed PV devices in a region.
