Zhang (2022) developed a wind power curtailment scheduling model that coordinates the use of heat-storage (CHP) and electric boilers for heating. This effectively expands the capacity of wind power accommodation into the
To further absorb the surplus wind power and alleviate restrictions, a comprehensive energy system optimization method for parks based on coordinated scheduling between sources and loads is proposed in this paper. First, the implementation of a heat-storage electric boiler on the source side further achieves the decoupling of heat and power.

Variety of forms available for central and room-based heating. Systems available for residential, commercial, or institutional settings.
Electric boilers (EBs) and electric heat pumps (EHPs) are potential to be deployed in northern China to solve the clean heating problem [1], [33]. Therefore, the adequacy study of MEC in the IES
To solve the problem of wind‐heat conflict during the heating period in the Three North area, an electric boiler with thermal storage (EBTS) is installed at the end of the grid where wind power
The northern regions of China face the challenges of the mismatch of the power supply and demand, as well as serious wind curtailment issues, caused mainly by the limitation of the "with heat to determine electricity" mode for combined heat and power generation during the winter season. To further absorb the surplus wind power and
The electric boiler and energy storage solutions built at the Vaskiluoto power plant site in Vaasa are extremely significant in scale in Finland. "With three electric boilers and a large thermal energy storage facility, we have an excellent heat production package at Vaskiluoto. This is a great example of making the most of our own power
An effective solution is to use electric heating boilers [88], [89] and equip them with heat storage [90], [91] combined with CHP. This will provide additional flexibility for heating supply and allow CHP units to further reduce their power generation [92]. The electric boiler has lower operational costs [93]. The working principle is to use
