Efficient smart grid technology - Controlling the energy balance in the isolated grids

This decentralised demand side management technology maintains the energy balance for more renewable energy at lower cost and carbon emissions.

This solution consists of three elements. First, a controller modifies the operation time of flexible electricity consumers (pumping, cooling, heating, charging of batteries – e.g. electric vehicles, time flexible processes like washing) or generators (combined heat and power plants – CHP) to respond to the current availability of energy. This controller can be an add-on electronics box or a piece of software integrated in the existing equipment controller by its supplier. Before that, a device generates the "Balance Indicator" (BI). This indicator, calculated through an algorithm, describes the current status of the grid. The controller takes this indicator as input data to decide when the appliances should function. The third element is a dedicated or firmware-updated “smart meter” able to read the BI and fix dynamic tariff of the electricity.
