Abstract
Conference Title: 2018 IEEE Power & Energy Society General Meeting (PESGM) Conference Start Date: 2018, Aug. 5 Conference End Date: 2018, Aug. 10 Conference Location: Portland, OR, USA This paper proposes a two-level Volt/Var control strategy in distribution networks considering the integration of intermittent renewables. It combines central and local control schemes. The central control collects loads and distributed generation (DG) measurements to optimize reactive power set-point of DG units to keep voltages within allowable limits. In addition, the central control uses a scenario-based approach to optimize local control parameters. This strategy considers the uncertainty related to photovoltaic (PV) systems, which is applied to a radial distribution feeder with high PV penetration. Simulation results verify the effectiveness of the proposed strategy in regulating voltage within limits and dealing with the fluctuation of DGs.
