Voltage Management Strategy for Distribution Network with TCLs Equivalent Energy Storage Model

Abstract

This paper introduces a voltage regulation strategy with thermostatically controlled loads (TCLs) equivalent energy storage model to alleviate voltage magnitude. Then, a voltage management model incorporating TCLs is developed as a multi-objective optimization model that collectively minimizes demand response (DR) cost, network loss and voltage deviation. Compared with existing methods, the proposed method achieves lower network loss and maintains safe voltage levels under renewable power injection. Finally, the proposed method is verified by testing examples.
