Precision laboratory power testing instruments featuring advanced regenerability, high frequency response, and bidirectional control loops optimized for demanding industrial clusters in Turkey.
Turkey's Green Energy Transition and Grid Simulation Demands
The industrial landscape in Turkey is experiencing an unprecedented structural pivot towards electrification, decarbonization, and grid modernization. Driven by the ambitious national strategies laid out by the Ministry of Energy and Natural Resources (ETKB), Turkey's commitment to wind and solar PV expansions (such as the YEKA initiatives) requires a highly resilient grid framework. However, integrating massive capacities of renewable, variable power systems introduces substantial power quality complications, transient events, and safety risks to local grids operated by TEİAŞ (Turkish Electricity Transmission Corporation).
To safely test, validate, and certify grid-tied devices such as solar inverters, wind turbine energy converters, and energy storage systems (BESS), manufacturers and research laboratories need sophisticated testing platforms. A Regenerative AC Grid Simulator is the definitive instrument to achieve this. By functioning as a fully programmable four-quadrant bidirectional AC power source, it emulates diverse and extreme grid environments—voltage sags, frequency deviations, harmonics distortion, and high-frequency voltage fluctuations—while recycling up to 90% or more of the reactive and active test energy back to the local utility grid. This saves substantial power costs during high-capacity endurance runs.
Why Four-Quadrant Bidirectional Simulation Matters
Conventional AC sources can only source power (Quadrant I and II). When testing grid-tied utility systems (such as solar inverters that generate active power), a traditional source cannot sink this reverse power flow safely, requiring external passive dummy loads that convert energy into wasted heat. Our Regenerative AC Grid Simulators operate seamlessly in all four quadrants, serving as both a programmable AC source and a fully controllable regenerative electronic load.
- Simulates microgrids, utility grids, and marine grids.
- Energy recovery efficiency reduces heat emission inside Turkish testing labs.
- Fully compliant with TEİAŞ Connection Guidelines & European EN 50549-1/-2 regulations.

Macro-Level Industrial Solutions for Turkish Enterprises
Whether you are located in the bustling industrial zones of Kocaeli, Bursa, Ankara (OSTİM OSB), or Izmir (Aegean Free Zone), our Regenerative AC Grid Simulators address multiple macro-level industrial engineering challenges:
Grid-Tie Solar & Wind Inverter Validation
For manufacturers looking to export to European markets or integrate into Turkey's domestic YEKA networks, inverters must pass rigorous Low-Voltage Ride-Through (LVRT), High-Voltage Ride-Through (HVRT), and anti-islanding validation. The Sophpower Regenerative Simulator emulates instant voltage drops, sweeps, and phase jumps to evaluate inverter dynamic performance.
EV Charging Station (EVSE) Testing
Turkey's national electric vehicle sector (championed by Togg) is growing exponentially, creating demand for fast DC charger deployment and vehicle-to-grid (V2G) integrations. Testing chargers requires bidirectional AC/DC systems to mimic vehicle grid-backfeeding scenarios under variable regional voltages.
Aerospace and Defense Systems Testing
In Turkish defense hubs around Ankara (e.g., Aselsan, TUSAŞ, Roketsan), electronic systems require 400Hz frequency converter simulation to mimic aircraft and military vehicle AC power networks. Sophpower's variable-frequency capabilities provide high-resolution outputs ranging from 45Hz to 400Hz.

Frequently Asked Technical Questions
Get answer to fundamental questions regarding Regenerative Grid Simulation technology, certifications, and deployments in the Turkish market.
A standard AC source is unidirectional; it supplies power to a load but cannot absorb reverse power. A Regenerative Grid Simulator operates in all four quadrants. When the device under test (DUT)—such as a grid-tied solar inverter—produces energy, the simulator sinks this energy and returns it to the utility grid with low harmonic distortion. This design avoids the need for massive resistive load banks, reducing power bills and thermal management requirements.
Yes. Our regenerative simulators feature programmable voltage and frequency dynamics, enabling them to simulate voltage drops to zero volts, phase shifts, and frequency transients. This capability supports compliance testing according to TEİAŞ regulations, IEEE 1547, and European grid codes like EN 50549.
