Optimal Location and Sizing of Renewable Distributed Generators for Improving Voltage Stability and Security Considering Reactive Power Compensation

Abstract

The integration of renewable resources into the existing power distribution system is expanding to reduce gas emissions, treat climate change and satisfy the current global need for clean energy. If the location and size of these renewable generators are determined without considering uncontrollable reactive power compensation caused by their intermittent nature, the resultant power system may suffer from system instability and decreased reliability. Therefore, the issue of optimal location and size of renewable resources attracts great attention. In this paper, a methodology is proposed to optimize the locations and capacities of distributed renewable generators installed in conventional power distribution systems. In particular, uncontrollable reactive power compensation of these renewable resources is considered in this paper and managed through the proposed methodology to ensure power system reliability and stability. As a result, the proposed methodology reminds us of the importance of reactive power compensation by performing better in power losses reduction and the robustness of voltage stability against variable reactive power compensation.

The consequences and barriers of power system voltage stability in the integration of solar and wind energy: An in-depth analysis

“…To explore voltage stability considerations and preserve the dependability of the power system, integrating nondispatchable renewable energy instances requires grid improvements and the construction of voltage control devices (Yeganefar et al 2020). The ability of every connector to maintain its voltage level is known as voltage stability in the sensible range both during regular processes and after emergencies (Kwangkaew et al 2022).…”
