Chroma ATE Inc.

Energy-Hybrid PV Inverter & Micro Grid Simulation Test Solution

In recent years the alternative energy of photovoltaic and wind power generation are increased and fed into the grid; however, these types of energy often vary with the weather that would make the power grid unstable. To optimize the usage of alternative energy and balance the grid to achieve peak load shaving, various countries are starting to promote the energy-hybrid type of photovoltaic power and wind power storage system with the combination of intelligent house and electric vehicle power supply to structure a micro-grid while the Power Grid Laboratories are building the simulation test requirements.

Chroma ATE Inc. has been dedicated in developing and manufacturing test and measurement associated equipment for more than twenty-nine years. As a listed company, Chroma is specialized in power electronic tests involving with programmable AC source, DC power supply, AC/DC electronic load and battery charging/discharging systems, etc. along with assorted test solutions for various kind of industries. 

To create a Micro Grid Lab for simulation testing, the user needs to build a backstage monitoring software platform so that it can optimize the energy usage and solve the abnormalities occurred through the Micro Grid system. As to the key factors (sunshine, temperature, wind speed, power grid and load change) for environment simulation, following are the major simulators Chroma has put forward that can be integrated into another simulation software platform for setup and monitoring.

Regenerative Grid Simulator:

It allows the user to create a simulation power grid and isolate it from the Mains. Besides simulating the voltage/frequency change of various kinds AC output, it can also simulate the voltage transient and harmonic waveform/interharmonics distortion.

Wind Power Simulator:

It is suggested to use the Solar Array Simulator to work with the Inverter and change the sunshine conditions to fan related parameters such as wind speed.

Programmable AC Electronic Load:

It can imitate the household and commercial use nonlinear single/three-phase rectifier loads like LCD TV, home PC, LED lighting power, server system and EV charging station, etc. for energy accumulation photovoltaic and micro grid system simulation.
