Energy Management in Power Distribution Network via Volt-VAr-Watt Control

The growing concern for exponential load growth, depletion of conventional energy resources, security threats, and environmental concerns are compelling the development of efficient energy management tricks and techniques. These concerns have shifted the paradigm of renewable-based generation. These renewable energy-based electricity generations are mostly integrated into the distribution network as distributed generations (DGs). Therefore, an analysis of the impacts of DG placement while implementing Volt-VAr control (VVC) has been executed through the simultaneous application of conservation voltage reduction (CVR), DG, capacitor banks (CBs), and distributed static compensator (D-STATCOM). The combined application is called Volt-VAr-Watt control (VVWC), and the effectiveness of this method of control has been verified using techno-economic gain. Further, the exponential load model has been considered rather than considering the simple static load model. Five distinct operating scenarios have been tested under the proposed scheme of VVWC with IEEE-33 and IEEE-69 node systems. Rao-1 algorithm is adopted to select the optimal location and capacity for DG, CB and D-STATCOM. Static capacitors and D-STATCOM have been used as VAr compensating devices, and their integration with CVR has been tested distinctly. The simulation results indicate that the improvised results are obtained for D-STATCOM compared to static capacitors. The findings show that the integrated method of CVR, DG and D-STATCOM results in a significant techno-economic gain with reduced overall power consumption, line flows and network losses compared to the other cases.
