Power Plant Controllers: Enabler or Troublemaker? Commissioning, Compliance, and Real-World Lessons
As distributed energy resource (DER) plants continue to grow in size and complexity, power plant controllers (PPCs) have become central to achieving reliable and compliant operation. By coordinating multiple inverters within the plant and controlling plant behavior at the point of common coupling (PCC), PPCs serve as a critical enabler for meeting grid requirements and delivering expected performance.
However, in practice, PPCs can be just as much a source of challenges as they are a solution. Unlike inverters, PPCs lack standardized requirements and certification processes. Their functionality is highly configurable, and implementations can vary widely across projects and vendors. As a result, utilities are increasingly encountering issues during plant design review, commissioning, and field operation—including unexpected control interactions, performance mismatches, and oscillatory behavior.
This session brings together utilities and industry experts to share real-world experiences with PPC-controlled DER plants, highlighting both the benefits and the pain points. Panelists will discuss the lessons learned, with a focus on commissioning challenges, troubleshooting approaches, and strategies for improving performance verification and repeatability.
