Building a new power system with new energy as the main body reduces the regulation capacity of the power supply side

which will have a negative impact on the safe and stable operation of the system.It is urgent to implement demand response to mobilize the load side regulation capacity.Firstly

it introduces the significance and development direction of building a new power system

and analyzes the power demand response strategies

mainly including price based

incentive based

and enforcement based.Secondly

it studies key technologies for power demand response from six aspects: load control

load aggregator

virtual power plant and so on.Finally

it forecasts the power demand response.
