Abstract

The effective management of reactive power plays a vital role in the operation of power systems, impacting voltage stability, power quality, and energy transmission efficiency. Despite its significance, suboptimal reactive power planning (RPP) can lead to voltage instability, increased losses, and grid capacity constraints, posing risks to equipment and system reliability. Rigorous RPP methodologies can mitigate these challenges, resulting in tangible improvements in voltage profiles, system stability, and reduced losses. A comprehensive review of 20 technical articles published between 2020 and 2023 was conducted to compare and synthesize contributions to the field of RPP. The review highlighted the efficacy of strategic RPP approaches in reducing power losses, minimizing equipment malfunctions, and improving power quality, leading to substantial economic benefits—strategic planning approaches and integrating emerging technologies. For instance, examples include renewable energy sources and energy storage systems, which offer promising avenues for enhancing RPP and ensuring stability, reliability, and efficiency in power systems.

全面回顾微电网无功功率规划的进展与挑战

无功功率的有效管理对电力系统的运行起着至关重要的作用，影响着电压稳定性、电能质量和能源传输效率。尽管无功功率规划（RPP）具有重要意义，但不理想的无功功率规划（RPP）会导致电压不稳定、损耗增加和电网容量限制，给设备和系统可靠性带来风险。严格的无功功率规划方法可减轻这些挑战，从而切实改善电压曲线、系统稳定性并减少损耗。我们对 2020 年至 2023 年间发表的 20 篇技术文章进行了全面回顾，对 RPP 领域的贡献进行了比较和综合。综述强调了战略性 RPP 方法在减少电力损耗、最大限度地减少设备故障和提高电能质量方面的功效，从而带来了巨大的经济效益--战略性规划方法和新兴技术的整合。例如，可再生能源和储能系统为提高可再生能源发电能力和确保电力系统的稳定性、可靠性和效率提供了大有可为的途径。
