Specifically, the parameters of the general component model may be set according to the output characteristics of each power component to obtain a power sub-model corresponding to the power component, for example:
(1) aiming at a thermal power generation element, the output of a thermal power generating unit can be freely adjusted between the maximum output constraint and the minimum output constraint according to the requirement, wherein the maximum output and the minimum technical output of the thermal power generating unit are input according to the actual conditions according to factors such as a heat supply period, high-temperature weather and the like, the climbing rate is determined by the inherent characteristics of the thermal power generating unit, the non-electric input is sufficient, and other maximum electricity storage power, energy storage and power consumption power are zero, so the parameters can be set as follows:

wherein, PiSP(t) pumped storage or stored installed power, RCiSPFor storing storage capacity or energy, etaiSPFor energy storage conversion efficiency.
(5) For electric vehicles and electric heat storage models, the following parameters can be set:

and 102, under the condition that a target power element needs to be added to the power system, performing parameter setting on the universal element model according to the output characteristic of the target power element to obtain a target power sub-model.
As can be seen from the above discussion, the parameters of the conventional and common power components can be set based on the general component model to obtain the corresponding target power sub-model, so that when a power system needs to add a target power component, the target power sub-model can be constructed based on the output characteristics of the target power component to be configured according to the above method.
And 103, updating the production simulation model based on the target power sub-model to obtain a first target production simulation model.
Specifically, the production simulation model is:
Figure BDA0002447761510000083
the first target production simulation model is as follows:
Figure BDA0002447761510000091
wherein, the Pi(t) is the generated power of the ith power element at the time t, Ci(t) is the stored energy power of the ith power element at the moment t, the
Figure BDA0002447761510000092

Therefore, when the production simulation model is updated based on the target power sub-model, only the actual external output power (P) of the newly added target power sub-model is required to be updatedi(t)-Ci(t)) adding the target production simulation model to the power system side of the production simulation model to obtain the first target production simulation model.
In the embodiment of the invention, the production simulation model of the power system is formed by setting the universal element model and establishing independent sub-models for each power element in the power system based on the universal element model. Therefore, when the target power element needs to be added to the power system, the model can be updated only by establishing the target power sub-model based on the general element model and adding the target power sub-model to the production simulation model. In the process, when the target power element needs to be added, the submodel of the target power element does not need to be built again, and the direct updating can be realized on the basis of the existing production simulation model, so that the maintenance cost of the production simulation model is reduced.
Optionally, the updating the production simulation model based on the target power sub-model to obtain a first target production simulation model includes:
and updating the production simulation model based on the target power sub-model by taking the energy curtailment power value as an optimization target to obtain a first target production simulation model.
In the prior art, the problems of wind power wind abandonment and photovoltaic light abandonment are severe in partial regional power grids, and the wind power wind abandonment and the photovoltaic light abandonment mean that the power of wind power generation and photovoltaic power generation is easy to be influenced by the environment and is in continuous change, so that the wind power and the photovoltaic power are regarded as unstable power sources and cannot be connected to the grid.
Specifically, since the wind power generation element, the photovoltaic power generation element, and the like are greatly affected by the weather conditions, the generated power is large when the wind power and the illumination are sufficient, and the generated power is small otherwise. Therefore, in the conventional art, it is found that there is uncertainty in the output power of a power generation element, such as a wind power generation element or a photovoltaic power generation element, which is greatly affected by weather conditions. In contrast, in the prior art, in order to ensure the stability of the power consumption of the user, for the power generation elements such as the wind power generation element and the photovoltaic power generation element which are greatly influenced by the climate conditions, only a part of the generated power is used to ensure that the power generation elements can stably output a small power, and when the wind power and the illumination are sufficient, the generated excessive electric power is usually selected to be abandoned.
In order to avoid waste of power resources, in this embodiment, an optimization target may be set to be the minimum energy curtailment power value, and the production simulation model is updated based on the target power sub-model to obtain a first target production simulation model. I.e. with W2tAnd taking the minimum value as an optimization target, and optimizing the simulation model generated by the first target. Therefore, the resource waste in the power system can be effectively reduced.
Optionally, after the building the production simulation model, the method further comprises:
under the condition that the power system needs to reduce second power elements, updating the production simulation model to obtain a second target production simulation model, wherein the second target production simulation model is as follows:
Figure BDA0002447761510000101
wherein the second power element is any one of the at least one power element, W3tAnd generating the energy curtailment power of the simulation model for the second target at the time t.
In the power system, part of the traditional power generation elements may be eliminated due to the problems of low power generation efficiency, severe environmental pollution caused by the power generation process and the like. Therefore, when the second power element in the power system needs to be eliminated, the power sub-model corresponding to the second power element can be deleted in the production simulation model. Since the second power element no longer participates in the power generation in the production simulation model, but the electric power required by the power consuming device does not change, the generated power of the other power elements in the production simulation model will increase accordingly. Therefore, in order to avoid the blind increase of the output power of each power element, after deleting the submodel of the second power element, the production simulation model is optimized by taking the minimum energy curtailment power as an optimization target to obtain a second target production model, and the second target production model can simulate and output the actual output power of each power element in the power system, so that a worker can control the output power of each power element according to the simulation result, and the waste of power resources is ensured under the condition of meeting the power consumption requirement.
