Description

Assessment method and system based on building energy consumption flexible adjustment potential index
Technical Field
The invention relates to the technical field of power demand side regulation, in particular to an evaluation method and system based on building energy consumption flexible regulation potential indexes. In addition, an electronic device and a non-transitory computer readable storage medium are also related.
Background
In recent years, with the rapid increase of the total social energy consumption, taking a terminal energy consumption represented by a building as an example, the building energy consumption is rapidly increased every year due to the increase of the number of buildings and the improvement of the requirement of users on comfort level; meanwhile, the power consumption ratio of the building temperature control load is also increased year by year, so that the seasonal peak load at the power grid end is rapidly increased, and a double-load peak is easily formed in summer and winter. In addition, the electricity utilization behaviors of users in the building energy to the temperature control load in one day in the peak load seasons of summer and winter tend to be consistent, and the peak-valley difference of the daily load curve of the power grid is further enlarged. How to fully exert the energy consumption characteristic of a building body and the capability of temperature control flexible loads in the building to participate in the peak-valley difference regulation of a power grid becomes a problem to be solved urgently. On the other hand, along with the deep research on the energy consumption of the building body and the rapid development of the flexible load regulation and control technology, the whole building participating in the regulation and control of the peak-valley difference of the power grid becomes possible. Therefore, the evaluation index of the flexible adjustment potential of the building energy consumption is analyzed, so that the adjustment margin range of the whole building responding to the power grid peak-valley difference adjustment and control in the future adjustment and control period is evaluated, and the evaluation method has important significance for matching with the power grid peak-valley difference adjustment and control and relieving the power grid capacity increase and modification.
However, at present, for the problem that building energy consumption participates in the regulation of the side peak-valley difference of the power grid, research for evaluating the building regulation potential by considering the energy consumption of a building body is relatively less, and a related technology for evaluating the building flexibility regulation potential index by comprehensively considering the characteristic relative humidity of the building body and the thermal disturbance of various personnel is lacked. In addition, the air conditioner and the electric heating isothermal control load occupy a large proportion in the energy load electricity consumption of the building, and under the existing load regulation technology, the method is the most direct and effective method for enabling the building energy to participate in the side peak-valley difference regulation of the power grid by controlling the electricity consumption behavior of the temperature control load under the condition of sacrificing the comfort level of a user. Therefore, how to evaluate the flexible regulation potential of the building energy consumption by taking the whole building energy consumption as an object and considering the energy consumption characteristic of the building body and the regulation potential of the internal temperature control flexible load becomes an important subject for researching participation of the building energy consumption in the regulation of the grid side peak-valley difference.
Disclosure of Invention

The three models forming the building energy flexible adjustment potential index are respectively explained below.
And adjusting the potential model aiming at the temperature control load of the building. When building energy flexible adjustment evaluation is carried out, firstly, a user must be ensured to be adjusted under a comfortable temperature condition, a temperature comfortable interval of the user often has a range, and the invention utilizes the temperature range of the user to carry out demand side response. When the load of the power grid side is in the peak time period, the power grid side hopes that the user properly reduces the power consumption to cut down the power consumption peak, so that the user can properly sacrifice some comfort level and reduce the power consumption, thereby reducing the load of the power grid side in the peak time period; when the load of the power grid side is in the valley period, the power grid side hopes that the user appropriately increases the power consumption to fill the power consumption valley, so that the user can adjust the indoor temperature to the optimal temperature comfort interval, and the load of the power grid side in the valley period is increased. Therefore, a range limit for the ambient temperature at which the user is located must be given. For example, the standard parameters for determining the indoor comfort environment are shown in table 1.
TABLE 1 Standard parameters of indoor comfort Environment
Figure BDA0002974947010000205
As can be seen from table 1, the indoor comfortable environment parameters are classified into two types, i.e., heating condition and cooling condition. Wherein, indoor comfortable grade divide into the two-stage respectively under heat supply operating mode and cooling operating mode, under the heat supply operating mode, I level comfort level temperature is higher than II level temperature comfortable interval, under the cooling operating mode, I level comfort level temperature is less than II level temperature comfortable interval, under each comfortable grade, all has corresponding relative humidity scope and wind speed scope.
Because the design parameters of the indoor comfortable environment are divided into a heat supply working condition and a cold supply working condition, the building temperature control load regulation potential is developed respectively aiming at the two scenes of the cold supply working condition and the heat supply condition.
(1) Building temperature control load regulation potential under cold supply working condition
In the embodiment of the invention, in consideration of practical situations, the indoor temperature in summer is difficult to always be within the range of the grade I or II temperature comfort interval in the design specification, the temperature interval of which the indoor temperature is lower than the grade I temperature comfort interval is called as a low-temperature uncomfortable area, and the temperature interval of which the indoor temperature is higher than the grade II temperature comfort interval is called as a high-temperature uncomfortable area. Therefore, the indoor temperature comfort region in the cooling mode is divided as shown in fig. 3 below.
In each temperature range divided under the cold supply working condition, the building energy consumption can correspondingly increase the refrigerating capacity and reduce the refrigerating capacity. According to the above, the building can increase the cooling capacity and decrease the cooling capacity, which are composed of three parts, namely the building energy consumption in summer, namely, the aforementioned Qcl,tThe cold energy storage equipment of the building can increase the refrigerating capacity and reduce the refrigerating capacity and useThe refrigerating capacity can be increased and decreased by controlling the temperature control load.
