Abstract:
In order to achieve the scenario of high- proportion distributed generations being consumed in distribution networks, this paper proposed a coordinated configuration method of cyber and physical equipment in distribution networks based on interval robust control, making full use of the flexibility of energy storage in the primary side and the active regulation in the secondary side. First, a comprehensive economic configuration model of the distributed generation control and energy storage was established. Then, considering the uncertainty of sources and loads, a robust optimal operation model was established with the constraint of the risk level of voltage exceeding. And a two-layer optimization model was built. The solution was based on the differential evolution algorithm. Finally, the effectiveness of the model was verified by taking the IEEE-33 node power distribution system as an example. Simultaneously, the impact analysis of different acceptable risk levels and equipment prices on the configuration was given. The research results could provide a useful reference for the economic consumption of distributed generations in the distribution networks.
