Building related charging loads, such as charging rooms, represent a significant way of making electricity demand and grid supply match.
Demand side management (DSM):
Demand-side management refers to adopting measures to improve consumption efficiency on the demand side by responding to electricity generation. Changing consumption patterns reduces overall electricity consumption and therefore demand, but meets the same consumption function. This could include but not limited to;
- A reduction in electrical consumption of traditional appliances
- Increase in time-of-use appliances and electronic devices
- Plug-in electric vehicles grid balancing
- Local renewable electricity generation
- Control devices and platforms • Electricity storage technologies.
Using this capability to ensure that electricity input to the grid matches the electricity demand. This results in a reduction in carbon emissions compared to conventional grid balancing which involves ramping up existing fossil fuelled power plants.
Run time management:
This is a type of control that limits the hours that a piece of equipment is able to run. This would involve individual setting following a predefined time schedule including fixed preconditioning phases.
