Product Categories:Intelligent Micro-grid Control
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.Limit solar power output as necessary using selective enable or power limit set point.
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.Frequency adjustment, use secondary load or energy storage, stabilize the frequency.
Control micro-grid assets to meet utility interaction objectives:
cost minimization with time-of-use (TOU) rates
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.
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.
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.
The controller can be implemented in a simple manner to achieve an increase in renewable energy or load.
