100% Renewables on your Grid Today
PI Coresight was renamed PI Vision in 2017
We describe a real time control system for power systems based on a tightly integrated PI System. The system is working on a renewable power plant that includes 8 three-MW wind turbines and an 11 MW/4.5 MWh Li-ion energy storage system. Power control is via nine inverters with both real and reactive power inputs. The system controls power discharge due to sudden changes in wind speed. This mitigating control function is applicable to most power systems with varying loads or varying distributed generation from wind or solar generation. The system includes “semi-firm” and “firm” power controls enabling the system operator to hold constant power demand. The controller reduces the variance of the power injected into the grid, thereby minimizing consumption of fossil fuels for regulation. The system also controls frequency. The controller is tightly integrated with the PI System and runs on a single substation hardened PC with flash drives. Configuration of the control system is through Asset Framework (AF) and all parameters in the control system are PI Tags. PI ProcessBook, PI Coresight and a custom high-speed interfacing to both AF and the controller and written using the PI AFSDK, display real time information to the operator. For control, the system uses real time 60 Hz PMU data from existing standard relays and includes an innovative automatic “ride-through” function to handle short interval missing data.

Raymond de Callafon
Dr. de Callafon is involved in teaching and research that cover many aspects in signal processing and real-time control. His research interests include topics in the field of data-based dynamic modeling (system identification), parameter and state estimation (data assimilation) and automation (adaptive control). He directs the System Identification and Control Laboratory (SICL) at the Dept. of Mechanical and Aerospace Engineering (MAE) and the Sychrophasor Grid Monitoring and Automation (SyGMA) laboratory at the San Diego Supercomputer Center. The work and the laboratories of de Callafon demonstrate a wide range of data intensive efforts in signal processing and control in both engineering applications (mechanical, audio, aerospace and electric grid systems) and earth science applications (oceanographic and wildfire monitoring).
