Ontech Intelligent Micro-grid Controller System can help customer set up a stable micro-grid system. 

This system support wind turbine\PV\diesel or gas generator, micro turbine, CHP, energy storage and other distributed energy resources.

Optimal diesel generator dispatch, including diesel-off operation when feasible

Receive the cloud control strategy and the integration of distributed control strategy as local control, achieve plug and play.

Prioritization of loads, with ability to designate critical and non-priority loads.  

Automatic load shedding as necessary to avoid system overload.

Limit wind power output as necessary using selective enable or power limit set point.

Functions

State-of-Charge (SOC) management of energy storage systems

Control multiple secondary loads to maximize renewable energy utilization and minimize storage requirement

Seamless transition between generator-on and generator-off modes of operation

Seamless transition between grid-connected and islanded operation

Load forecasting, according to the historical data, predict the next moment micro-grid load, and adjust the distributed power.

Control micro-grid assets to meet utility interaction objectives:
demand limiting
export limiting
cost minimization with time-of-use (TOU) rates

Characteristics

Peak shaving
At the lowest cost period charge the battery, and in the highest cost period the energy storage discharge, so as to save the electricity charge.

Electrical Safety

In the case of Grid fluctuations, such as frequency failure, voltage failure, micro-grid will automatically cut off the connection with the Grid to protect the electrical equipment from damage.

Remote monitoring

In any position to remotely monitor the operation of micro-grid.

Fault mail notification

Micro-grid failure, will quickly inform the operation and maintenance personnel by mail.

Historical data record

Record the historical data, help to know the energy consumption, and then analysis it to guide the production.

Minimum cost to run

The micro-grid controller selects a combination that provides the lowest cost of energy. If possible, always use PV, according to capacity and cost to select the grid, diesel and energy storage.

Automatic fault adjustment

If the component fails, the controller can automatically adjust and select other required components to provide a stable power supply.

Easy expansion

The controller can be implemented in a simple manner to achieve an increase in renewable energy or load.
