This is an Online Course. In lieu of recent developments with COVID-19, for the health and safety of our speakers and attendees, we have decided to move many of our events to Online Courses.

This course will highlight how Plant Controls and Supervisory Control and Data Acquisition (SCADA) systems provide the critical capability to control, monitor, and analyze the performance of solar and solar combined with storage plants. Throughout the day and a half program, attendees will learn everything from PV plant and storage basics, functional requirements of the plants, and how these requirements are implemented in plant controls and SCADA systems.

All attendees will leave the class having a holistic understanding of the Plant Controls and SCADA systems that pertain to solar plants and solar plus storage plants. It will benefit you whether you’re an operator or a professional who needs a detailed understanding of operation, reliability, and stability of a PV and storage plant, or a sales professional who needs a better understanding of the system to better serve customers. The goal by the end of the course is to have all attendees develop a working familiarity with the key concepts related to this topic.

Learning Outcomes  

  • Review the key components of PV plants and PV-storage plants
  • Discuss the functions of PV plants, including energy harvest, regulations, grid disturbance, and frequency response
  • Study the architecture, functions, components, data, and instrumentation of Plant Controls and SCADA systems for PV plants
  • Examine the key functions of control system of a PV plant such as active power control, ramp rate controls, voltage and reactive power control, advanced capabilities, and more
  • Discuss the impact of adding storage to PV plants
  • Evaluate the integration between control systems and SCADA including battery management systems, impact on the grid, and dispatch scheduling
