Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0090] As Figure 1 shown, a comprehensive energy scheduling method for a park, the method includes:

[0091] Construct a classification and grading regulation capacity model for electro-thermal-cooling regulation resources participating in the spot market, including: energy storage device model, electric vehicle charging pile model, air conditioner model, ice storage cooling device model, ground source heat pump model, and heat storage electric boiler model;

[0092] Based on the classification and grading regulation capacity model, construct a classification and grading optimization scheduling model for electro-thermal-cooling regulation resources in the park's comprehensive energy system under the spot market, optimize and solve the proportionality coefficients set for each regulation resource to participate in the day-ahead, intraday, and real-time market regulations, and obtain the optimal regulation proportionality coefficients;

[0093] According to the spot market signals, based on the optimal regulation proportionality coefficients, with the goal of minimizing the comprehensive energy consumption cost in each stage, solve the classification and grading optimization scheduling model for electro-thermal-cooling regulation resources in the park's comprehensive energy system in the day-ahead, intraday, and real-time stages, output the scheduling plans for the classification and grading resources, and schedule the park's comprehensive energy according to the scheduling plans.

[0094] During specific implementation, the introduction is as follows:

[0095] Step 1: Construct a classification and grading regulation capacity model for electro-thermal-cooling regulation resources such as energy storage, air conditioner, ice storage cooling, ground source heat pump, heat storage electric boiler, and electric vehicle charging pile participating in the spot market.

[0096] Step 2: Construct a classification and grading optimization scheduling model for the electric, heating and cooling regulation resources of the park's integrated energy system under the spot market, optimize and solve the proportional coefficients of each regulation resource participating in the day-ahead, intraday and real-time market regulation settings, and obtain the optimal regulation proportional coefficient.

[0097] Step 3: Based on the spot market signals, solve the classification and grading optimization scheduling model of the electric, heating and cooling regulation resources of the park's comprehensive energy system in the day-ahead, intraday and real-time stages. With the goal of minimizing the comprehensive energy cost in each stage, determine the power generation and consumption plan of the classified and graded resources to achieve low-error response.

[0098] In step 1, the classification of electric, heating and cooling regulation resources specifically refers to dividing the above electric, heating and cooling regulation resources into two categories according to the speed of regulation capacity: fast regulation type and slow regulation type regulation resources. Considering that there is a delay in the dispatch of heat and cold energy and the dispatch cycle is relatively long, the electric energy regulation resources such as energy storage and electric vehicle charging piles are classified as fast regulation type regulation resources, while the heat and cold energy regulation resources such as air conditioners, ice storage, ground source heat pumps, and thermal storage electric boilers are classified as slow regulation type regulation resources; the classification of electric, heating and cooling regulation resources refers to further classifying the fast / slow regulation type regulation resources into three levels: shallow / medium / deep according to the degree of participation in the spot market. Specifically, the part of the regulation resources participating in the day-ahead market dispatch can be classified as shallow, which is mainly used to balance the medium- and long-term supply and demand of the power system; the part of the regulation resources participating in the intraday market dispatch can be classified as medium, which is mainly used to cope with short-term supply and demand fluctuations; the part of the regulation resources participating in the real-time market dispatch can be classified as deep, which requires it to have higher flexibility and response speed to cope with instantaneous supply and demand changes.

[0099] In step 1, the initial values ​​of the shallow / medium / deep adjustment ratios of various types of electric heating and cooling adjustment resources in the spot market are set, and then this ratio is optimized and adjusted in step 2. Among them, the slow-adjusting resources cannot achieve minute-level demand response, and the initial value of the deep adjustment ratio of the slow-adjusting resources is set to 0, and the initial values ​​of the shallow and medium adjustment ratios are both set to 50%; the fast-adjusting resources are more involved in the scheduling of the real-time market, so the initial value of the shallow adjustment ratio of the fast-adjusting resources is set to 40%, and the initial values ​​of the shallow and medium adjustment ratios are both set to 30%.

[0151] It should be noted that in step 3, in the day-ahead optimization stage, the integrated energy system electro-thermal-cooling regulation resource classification and grading optimization scheduling model in the park takes the minimum comprehensive energy consumption cost of the park on the second day as the objective function, and takes into account the operation constraints and operation economic costs of the electro-thermal-cooling regulation resources. The optimal power purchase curve of the power grid calculated by the day-ahead optimization model on the second day can be used for the electricity declaration in the day-ahead market. Since the response speed requirement for the regulation resources in the day-ahead optimization stage is not high, only the electricity balance needs to be achieved, and all electro-thermal-cooling resources can participate in the regulation in the day-ahead optimization stage, and the regulation coefficient is set as γ DAM , γ ∈ {α, β}, where α refers to fast-regulation type resources such as energy storage and electric vehicle charging piles, and β refers to slow-regulation type resources such as air conditioners, ice storage, ground source heat pumps, and heat storage electric boilers. These regulation coefficients are decision variables in the day-ahead optimization model, and the regulation plans of the day-ahead electro-thermal-cooling regulation resources and the optimal power purchase curve of the power grid on the second day are obtained by solving the day-ahead optimization model.

[0152] In the intraday optimization stage, the classification and grading optimization scheduling model of the electro-thermal-cooling regulation resources in the park integrated energy system aims to minimize the overall intraday energy consumption cost. Based on the cleared day-ahead electricity price, the power generation and consumption arrangements in the intraday optimization stage are obtained, including the intraday power purchase plan curve and the intraday energy regulation plans of various electro-thermal-cooling resources. The intraday optimization model involves the power balance of electricity, heat, and cooling. The electro-thermal-cooling resources can still participate in the regulation in the intraday optimization stage, and the regulation coefficient is set as γ IDM , where γ ∈ {α, β}. The optimal regulation plan of the intraday electro-thermal-cooling regulation resources and the intraday 24-hour power plan curve are obtained by solving the intraday optimization model.

[0153] In the real-time optimization stage, the classification and grading optimization scheduling model of the electro-thermal-cooling regulation resources in the park integrated energy system aims to minimize the comprehensive energy consumption cost. Based on the ultra-short-term prediction of the photovoltaic power output, the intraday power generation and consumption plan are corrected every 15 minutes to achieve the coordination of the global optimization in the intraday stage and the local optimization in the real-time stage. Since the real-time optimization model has a 15-minute cycle and requires a high regulation speed for the regulation resources, only the fast-regulation type electric energy regulation resources participate in the regulation, and the regulation coefficient is set as α RTM , and the optimal regulation plan of the real-time electro-thermal-cooling regulation resources is obtained by solving the real-time optimization model, updating the power generation and consumption plan and the real-time market electricity price of the park integrated energy system to minimize the energy consumption cost.
