Wherein, the adjustable load potential model is to construct an objective function with the goal of maximizing the sum of adjustable loads of all adjustable load equipment that can participate in the regulation during the response period, and construct constraints for the objective function, through all The objective function is constructed by the constraint conditions.

A method for determining a load regulation scheme provided by the present invention can be used in a ceramic enterprise. This embodiment takes a ceramic enterprise as an example, and the specific implementation is as follows:

Step S1, based on the obtained power consumption load data of the adjustable load equipment, using a pre-built adjustable load potential model to determine the maximum adjustable load per unit time in the response period, including:

Obtain the electricity load data of the adjustable load equipment; the electricity load data includes: load data, production data and load adjustment performance parameters; the load data includes: the load amount and load power of the load equipment; the production data includes: the maximum load of the load equipment Inventory capacity, current inventory capacity of load equipment and inventory consumption rate of load equipment; load regulation performance parameters include: link response duration.

Substitute the obtained electricity load data of the load equipment of the ceramic enterprise into the pre-built adjustable load potential model to calculate the maximum adjustable load per unit time during the response period; the adjustable load potential model is as described in Example 1;

In step S2, based on the maximum adjustable load per unit time of the response period, the demand response cost is calculated through a predetermined cost calculation formula, which specifically includes:

Maximum adjustable load.

Because in ceramic enterprises, the economic cost of load adjustment of ceramic enterprises mainly includes: fixed cost and variable cost. The fixed cost is the one-time investment cost of controller transformation and control device, and the specific value is determined according to the number of transformation points. The controller and the control device are devices or power-off switches that control the start and stop of the adjustable load. Variable cost is to measure the impact of industrial load power adjustment on the production capacity of industrial production. In the present invention, the cost of each scheme is mainly reflected in the calculation of variable cost. In this embodiment, the ceramic enterprise participates in the upward or downward adjustment. In different directions, the variable cost of adjustment is divided into two categories: the variable cost of economic cost participating in downward adjustment and the variable cost of economic cost participating in upward adjustment;

Users who participate in the downward adjustment can make up for the decline in production by rescheduling shifts, etc. Therefore, when the power of production equipment is adjusted downward, the unit value loss is mainly due to the increase in management costs caused by the rescheduling. Therefore, the participation in the downward adjustment is The variable cost of the economic cost of the The ratio is determined by the difference between the electricity price difference and the electricity price difference during production during peak and valley periods.

The variable cost of participating in the economic cost of downward adjustment is determined by the following costing formula:

In the formula, C _{v_down} is the load unit value loss (yuan/kWh); n is the total number of workers who need to be shifted; S _{x, down} is the hourly wage of the xth overtime worker (yuan/hour); ΔP _E is adjustable Power (kW); F _peak is the electricity price (yuan/kWh) during peak period production; F _valley is the electricity price (yuan/kWh) during valley period.

Users who participate in the upward adjustment can make up for the decline in output by working overtime and other methods, and the additional manpower required needs to be included in the cost, and when the power of the production equipment in the ceramic enterprise is adjusted upward, because it occurs in the load trough period, this time is generally the factory's During off-hours, workers will be paid extra for overtime. Therefore, the variable cost of participating in the economic cost of upward adjustment is based on the ratio of the maximum adjustable load per unit time in the response period and the pre-obtained sum of the hourly wages of all workers who currently need to work overtime to obtain the ratio of the two; It is determined based on the difference between the ratio and the electricity price difference of electricity used during production during peak and valley periods.

The variable cost of participating in the economic cost of upward adjustment is determined by the following costing formula:

In the formula, C _{v_up} is the cost of new electric energy for the load (yuan/kWh); n is the total number of workers who need to work extra overtime; S _i,up is the hourly wage of the _i -th overtime worker (yuan/hour); Adjusted power (kW); F _peak is the electricity price (yuan/kWh) during production during peak hours; F _valley is the electricity price (yuan/kWh) during production during valley hours.

Based on the variable cost of participating in the downward economic cost and the variable cost of participating in the upward economic cost, it can be known that the calculation formula of the control cost _cv of the unit electricity of the load is:

In the formula, C _{v_down} is the unit value loss of the load, C _{v_up} is the cost of new electric energy for the load, and _ΔPE is the maximum adjustable load per unit time during the response period.

In step S3, the maximum adjustable load per unit time of the response period and the demand response cost are combined to construct a load adjustment scheme, which specifically includes:

Combining the maximum adjustable load per unit time in the response period of the ceramic enterprise at the current moment and its corresponding demand response cost to determine the load adjustment plan can provide a reference and an alternative for the ceramic enterprise to participate in the plan formulation of demand response, and also for other types of Industrial users can provide reference for similar demand response services, promote flexible interaction between industrial users and the power grid, and improve the benefits of both parties.
