PHIL System (Power Hardware In-Loop System) Case Study Brochure_EN_2022 V1

Product catalog summary

Overview: This document is a case study on the Power Hardware In-Loop (PHIL) system implemented in KIER Korea, focusing on a power grid simulation system using a 4 Quadrant Power Amplifier (PAV5000). The system integrates a PONOVO 4-Q amplifier, RTDS simulator, DC electronic load unit, and a photovoltaic (PV) inverter.

System Components:

4-Q Amplifier: Simulates energy feedback to the grid and can act as a power source when needed.
RTDS Simulator: Provides real-time simulation of the grid.
DC Electronic Load Unit: Consumes part of the energy generated by the PV system.
PV Inverter: Generates power for the system.

Operational Details: The PHIL system operates by balancing power between the PV inverter and the grid simulation. For instance, if the PV inverter outputs 9kW, the DC load consumes 6kW, and the 4-Q amplifier absorbs the remaining 3kW, ensuring power balance.

Key Functions:

The 4-Q amplifier can both sink and source power, simulating grid feedback and generation.
The system ensures that excess energy from the PV inverter is managed effectively.

PHIL System (Power Hardware In-Loop System) Case Study Brochure_EN_2022 V1-1

As the diagram above, the Grid-connected PV PHIL system experiment consist of a RTDS simulator, a PONOVO PAV5000 4-Q amplifier, a DC electronic load unit, a PV inverter, a programmable DC power supply unit, an ESS (Energy Storage System) and a programmable grid-connecting source sink unit. In the experiment, the 4-Q amplifier and simulator could simulate the real-time grid system. The PVPS (Photovoltaic power generation system) is composed by the PV inverter and the programmable DC power supply unit. The ESS (Energy Storage System) and the Programmable grid-connecting source sink unit are both used to compose the BESS (Battery energy storage system), which can provide power supply and energy storage for the Grid. The PAV 4-Q amplifier, DC electronic load unit, PVPS and BESS are paralleled connected so that the 4-Q amplifier could implement the dynamic conversion between sink mode and source mode.
