The heat accumulating electric boiler utilizes the electric energy in the night valley period as energy source, and the heat accumulating electric boiler can heat at night and supply heat in the day.
Because the controller of the electric heat storage boiler usually follows the temperature (water or solid) of the medium in the heat storage device and is adjusted by using a PID mode, the power fluctuation is large in the heat storage process, the prediction of the whole power curve is difficult, and the advance declaration of the T-1 day is not facilitated. Based on the above, the embodiment of the invention adopts a two-stage declaration strategy, and fully combines the characteristics of the electric power peak regulation auxiliary service market and the characteristics of the electric heat storage heating system.
Specifically, the historical heat demand of the electric heat storage boiler in each time period is obtained, and the tomorrow heat demand of the electric heat storage boiler is predicted according to the historical heat demand of each time period, wherein the predicted heat demand refers to the tomorrow heat demand of the electric heat storage boiler predicted based on the historical heat demand. Meanwhile, determining historical contemporaneous minimum heat demand of the electric heat storage boiler according to historical heat demand of each time period, wherein the historical contemporaneous minimum heat demand refers to minimum heat demand in the same time period. Then, a first operating period of the electric heat storage boiler in the first operating stage is determined based on the rated power, the thermal efficiency, the historical contemporaneous minimum heat demand, and the predicted heat demand of the electric heat storage boiler. It is understood that the first operation period refers to a period in which the electric heat storage boiler is operated at a rated power.
In one embodiment, a first operating period of the electric heat storage boiler in the first operating stage is determined based on the fixed power, the thermal efficiency, and the historical contemporaneous minimum heat demand if the historical contemporaneous minimum heat demand is less than the predicted heat demand.

Specifically, the historical contemporaneous minimum heat demand is compared with the predicted heat demand, and if the historical contemporaneous minimum heat demand is greater than the predicted heat demand, the rated power, the thermal efficiency, and the predicted heat demand determine a first operating time period of the electric heat storage boiler in a first operating stage, wherein the first operating time period is calculated as follows:
in the above formula, t: the first run length (minutes from morning zero) is an integer multiple of 15 minutes;
pr: rated power of the electric heat storage boiler.
Step S20, determining a second operation time of the electric heat storage boiler in a second operation stage according to the peak shaving time length and the first operation time length;

By determining the first operating time of the electric heat storage boiler at rated power, the benefit of the load aggregator or the user agent of the electric heat storage boiler is maximized, i.e. the benefit is increased.
Step S30, determining declared power of the electric heat storage boiler in a second operation stage according to the peak shaving time length, the heat efficiency, a preset coefficient, the predicted heat demand, the rated power and the first operation time length;
in order to guarantee the heat supply requirement, maximize the benefit and avoid energy waste caused by continuous high-power output, the embodiment of the invention determines the declared power of the electric heat storage boiler in the second operation stage according to the peak regulation duration, the heat efficiency, the preset coefficient, the predicted heat demand, the rated power and the first operation duration, wherein the total heat storage amount of the second operation stage is as follows:
in the above formula, n: the peak regulation time length;
0.25: presetting a coefficient;
t: the first operating time period (number of minutes from morning zero) is an integer multiple of 15 minutes;
pr: rated power of the electric heat storage boiler.

In one embodiment, the method further comprises:
and determining the maximum benefit of the electric heat storage boiler in the second operation stage according to the historical operation reference power, the historical average clearing price, the declared power, the peak shaving duration and the preset coefficient of the electric heat storage boiler.
Specifically, the maximum benefit of the electric heat storage boiler in the second operation stage is determined according to the historical operation reference power, the historical average clearing price, the declared power, the peak shaving duration and the preset coefficient of the electric heat storage boiler. The objective function of peak regulation profit maximization is as follows:
in the above-mentioned formula,

According to the embodiment of the invention, the maximum benefit of the electric heat storage boiler in the second operation stage is determined according to the historical operation reference power, the historical average clearing price, the declared power, the peak regulation duration and the preset coefficient of the electric heat storage boiler, so that the heat supply requirement is guaranteed, the benefit is maximized, and the energy waste caused by continuous high-power output is avoided.
Referring to fig. 2, fig. 2 is a schematic diagram of a reporting flow of the peak shaving auxiliary service of the electric heat storage boiler provided by the invention.
In the electric power auxiliary service market transaction, flexible loads at a user side can participate in the transaction, a load aggregator aggregates the flexible adjustable loads at the user side, receives a scheduling instruction of a power grid scheduling center, supports power grid peak shaving and obtains benefits, and the load aggregator needs to declare the adjusting capacity of the aggregated flexible loads at T day-1.
Because the controller of the electric heat storage boiler usually follows the temperature (water or solid) of the medium in the heat storage device and is adjusted by using a PID (proportion integration differentiation) mode, the power fluctuation is large in the heat storage process, the prediction of the whole power curve is difficult, and the advance declaration of the T-1 day is not facilitated. The regulation capacity declared by the load aggregator does not influence the normal energy use of the demand side, meanwhile, the benefit maximization is achieved, and meanwhile, the situation that the yield is influenced because the flexible load is assessed by a power grid due to improper declaration (for example, the yield of 15 minutes is zero when the flexible load does not reach +/-20% of declaration power in actual operation) is avoided.
Based on the above, the embodiment of the invention divides the operation of the electric heat storage boiler into two sections based on the overall heat load which is easy to predict, the base load section adopts rated power to operate, the tail load section adopts smaller power to operate, the two sections of operation time are in the transaction time period, and the maximum benefit can be obtained by the aggregator and the electric heat storage boiler body under the condition of fully ensuring the heat demand of the demand side.
In particular, due to the thermal inertia, if the boiler plant is operated with maximum power until the thermal storage means is full of heat, it may cause a waste of primary energy, raising the energy consumption. Therefore, the embodiment of the invention adopts two-section declaration, and after declaration, the output of the boiler can be regulated according to the two-section declaration power, wherein the rated power is used for heat storage in the first operation stage, so that the peak regulation benefit is maximized; and in the second operation stage, the heat is stored with smaller power, the heat is fully stored in the valley power and peak regulation time period, and energy waste caused by high-power heat storage is avoided.
A first operating phase:
the rated power Pr of the electric heat storage boiler, the first operation time period t and the heat storage amount are the historical same-period minimum heat demand cal _ min, and if the predicted tomorrow heat demand cal _ pre is smaller than the historical same-period minimum heat demand, the heat storage amount is 80% of the predicted tomorrow heat demand cal _ pre.
Pr: rated power of the electric heat storage boiler;
t: the first stage run length (minutes from morning zero) is an integer multiple of 15 minutes.
If it is
Then, then
If not, then,
the first operating phase is operated for a time period t at the rated power Pr.
A second operation stage:
an objective function: sum (0.25 power fe) peak shaver gain maximization;
the objective function of peak regulation profit maximization is as follows:
