The rapid growth of inverter-based resources like solar PV, battery storage, and wind requires precise validation of their grid interactions. We simulate DERs and utility-scale inverter controls under real-time conditions, capturing dynamic responses often missed in offline studies. Our HIL and CIL setups test compliance with standards such as IEEE 2800 and NERC PRC-024, verifying performance during voltage sags, frequency deviations, and fault ride-through. This process enhances stability and interoperability before field deployment.

HVDC links and Flexible AC Transmission Systems (FACTS) devices are critical for grid flexibility and stability. We develop and validate advanced control schemes for these technologies, ensuring effective voltage regulation, power flow control, and oscillation damping. Real-time CHIL testing in our RTDS Lab allows evaluation of dynamic performance under faults, switching events, and renewable variability. This rigorous process supports tuning, protection validation, and compliance before installation.

Robust microgrid and black start protocols enhance grid resilience and enable autonomous restoration after outages. We design sequences for safe system energization, including synchronization, load pickup, and protection coordination. Time-domain and real-time simulations verify these protocols across diverse scenarios, ensuring smooth voltage and frequency recovery. Our microgrid controls support islanded operation, dynamic load balancing, and seamless grid reconnection for critical facilities.

The PPC coordinates renewable plant outputs to maintain grid stability and compliance. We conduct closed-loop testing of PPC logic and communication interfaces using HIL and CIL simulations. Testing replicates grid disturbances and control commands, validating performance under ramping, curtailment, fault ride-through, and reactive power support. Compliance with IEC 61850, Modbus, DNP3, and regional grid codes is verified to reduce commissioning risks.

Integrating battery energy storage systems (BESS) and distributed energy resource management systems (DERMS) demands thorough interface validation. We simulate real-time dispatch, frequency response, and grid support functions using hardware and controller-in-the-loop techniques. Communication protocols such as IEEE 2030.5, OpenADR, and DNP3 are tested alongside control functions like state-of-charge management and ramping. This ensures reliable coordination, compliance, and operational readiness.
