Although PV systems are one of the most widely used alternatives as a renewable energy source due to their well-known advantages, there are significant challenges to address related to voltage fluctuations and reverse power flow caused by high PV penetration scenarios. As a potential solution to this problem, an active power management strategy is proposed in this work using a residential cluster as a benchmark. The proposed strategy is analyzed and experimentally verified, offering a simple way to reduce the voltage fluctuations by regulating the active power delivered by the PV system, achieving also relevant functionalities for the system, such as the regulation of the DC bus voltage, maximum power point tracking (MPPT), synchronization with the grid voltage, detection of high penetration conditions, and a simple strategy for the main controller with an effective performance. The proposal system shows satisfactory results being able to maintain grid voltage fluctuations within the voltage standard specifications.

高渗透场景下光伏系统的主动电源管理

尽管光伏系统因其众所周知的优势而成为最广泛使用的可再生能源替代方案之一，但由于高光伏渗透率场景引起的电压波动和反向功率流，仍存在重大挑战。作为该问题的潜在解决方案，本工作中提出了一种以住宅集群为基准的主动电源管理策略。对所提出的策略进行了分析和实验验证，提供了一种通过调节光伏系统提供的有功功率来减少电压波动的简单方法，还实现了系统的相关功能，例如直流母线电压的调节、最大功率点跟踪 (MPPT)，与电网电压同步，检测高穿透条件，以及具有有效性能的主控制器的简单策略。该提案系统显示出令人满意的结果，能够将电网电压波动保持在电压标准规范内。
