Optimal Coordinated Voltage Control of Distribution Networks Considering Renewable Energy Sources
Main Article Content
Abstract
In light of the pressing concerns regarding global warming and the diminishing availability of fossil fuels, there has been a notable surge in the adoption of distributed generation (DG) systems, which harness clean and renewable energy sources. These systems are strategically placed in close proximity to end-users, thereby reducing power losses. However, without effective control mechanisms, issues such as voltage instability and increased power losses can impede the efficient functioning of the power grid. In this paper, an innovative approach termed Optimal Coordinated Voltage Control (OCVC) designed for distribution networks integrating dispersed renewable energy sources. Employing a genetic algorithm (GA) methodology and implementing multi-core simulation using the open-source platform OpenDSS, this method aims to optimize the settings of voltage control devices remotely. Moreover, it accounts for dynamic variations in both load and generation patterns through day-ahead scheduling. To evaluate the efficacy of the proposed technique, simulations are conducted on a test distribution network featuring the integration of DG systems.
