摘要：
Distributed photovoltaic(PV) generation is usually connected to distribution network, and the rapid development of grid-connected PV will bring great challenges to the safe operation of distribution network, so research of the distributed PV generation absorption capacity has become an important part of the development of distributed PV generation. Consequently, considering the incomplete information in distribution network, we propose a capacity analysis method of distributed PV generation integrated into distribution network considering energy storage configuration mode based on fusion of multiple data sources. Moreover, we optimize the absorption capacity analysis model of the distributed generation via integration of real-time data and historical data from power grid dispatching system, distribution automation system, distributed generation monitoring, and control system, and via integration of electricity data and historical data from metering system, marketing system, and load control system. Considering the ability of energy storage in power system’s voltage regulation in different configuration modes, such as the grid side and the distributed generation side, the acceptance ability of distribution network is analyzed by taking the target value of voltage deviation and voltage fluctuation as the quantitative calculation, the safety index of short circuit current and branch current carrying capacity as the constraint, and finally by taking the economic and reliability indexes as the checksum. Finally, the experimental results from the actual distribution network verify the effectiveness and feasibility of the proposed method. The results reveal that, compared with the energy storage configuration on the distributed generation side, storage allocation in the grid side can improve the distributed PV accommodation capacity of the distribution network, and the accommodation capacity has been improved by 42.5%. © 2018, High Voltage Engineering Editorial Department of CEPRI.
