High penetration of distributed generation (DG) can cause fast voltage changes in distribution systems. Inverter-based DG can be a significant source of reactive power, which brings new opportunities to improve the performance of the distribution system. An integrated control strategy is formulated for the coordinated control of both distribution system equipment and inverter-based DG. The control strategy combines the use of inverter reactive power capability with the operation of voltage regulators in order to improve the expected value of a desired figure of merit (e.g., system losses) while maintaining appropriate system voltage magnitudes, by formulating chance constraints on the voltage magnitudes. The effectiveness of the proposed method is validated using the IEEE 123-node radial distribution system.
