Owing to the development of new technologies such as 5G/6G and IoT [41], demand response (DR) is a potentially attractive approach to deal with the critical situation posed by EV charging by adjusting the electricity price or providing incentives to regulate the charging load and alleviate the pressure on the power grid [7], [8].

IEA. Licence: CC BY 4.0. Globally, the pace of demand response growth is far behind the 500 GW of capacity called for in 2030 in the Net Zero Scenario, under which the need for electricity system flexibility – defined as the hour‐to‐hour change in output required from dispatchable resources – more than doubles to 2030.
The International Energy Agency states: "demand response refers to balancing the demand on power grids by encouraging customers to shift electricity demand to times when electricity is more plentiful or other demand is lower, typically through prices or monetary incentives.". Demand response programs, along with smart

A storage heater or heat bank (Australia) is an electrical heater which stores thermal energy during the evening, or at night when electricity is available at lower cost, and releases the heat during the day as required. Accumulators, like a Hot water storage tank, are another type of storage heater but specifically store hot water for later use.
Additionally, a small number of policies provide subsidies for energy storage charging volume, as well as response subsidies for installing energy storage
The role fulfilled by demand response and energy storage has become increasingly critical and cost-effective, especially at high penetrations of solar and wind power generation. At this time, studies have discovered that the power grid can support roughly 30% of the current annual electricity demand brought about by variable generation.
Known as demand response programs, they help avoid overload, reduce emissions, and avoid expensive equipment upgrades. Large energy users can participate in a demand response program and receive payments for reducing the use of electricity from the grid during periods of highest electricity demand. These periods of extreme energy use
