Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a power configuration method of a new energy base delivery scheme provided in the present invention, as shown in fig. 1, the method includes steps 101 to 107, which are as follows:
step 101: and acquiring and generating a new energy delivery base simulation model according to the basic parameters of the new energy delivery base, and setting the authority of the new energy delivery base simulation model.
In this embodiment, basic parameters of the new energy delivery base are obtained based on the existing new energy delivery base, where the basic parameters of the new energy delivery base include specified delivery channel capacity, number of hours of channel utilization, a load characteristic curve of 8760 hours per year of a receiving end, a 8760-hour output characteristic curve of new energy per year of a sending end, a channel line loss rate, a maximum power generation rate, a minimum power generation rate, and the like. And generating a corresponding new energy delivery base simulation model by inputting the acquired basic parameters of the new energy delivery base.
In this embodiment, the generated new energy delivery base simulation model is subjected to power transmission permission setting, so that power transmission to the power grid at the sending end is not performed in the new energy delivery base simulation model, and it is ensured that a power supply configuration scheme for performing the intended operation in the new energy delivery base simulation model is independent of the power grid at the sending end and only receives the support of the power grid at the sending end, and the power grid at the sending end is not subjected to power back transmission, so that reasonable utilization of power resources is realized, and meanwhile, peak regulation pressure of the power grid at the sending end is reduced.
Step 102: and judging whether the new energy ratio and the comprehensive power abandon rate of the new energy in the simulation operation of the new energy delivery base simulation model of the first power supply configuration scheme meet corresponding preset thresholds.
In this embodiment, a first power configuration scheme of the new energy delivery base is first constructed, and relevant parameters are set for the first power configuration scheme. As an example in this embodiment, thermal power configuration capacity is set in a first power configuration scheme, where an initial setting capacity of the thermal power configuration capacity is 0; setting wind power configuration capacity and photovoltaic configuration capacity in a first power configuration scheme so that the ratio of the wind power configuration capacity to the photovoltaic configuration capacity meets an initial setting ratio, wherein the initial ratio of the wind power configuration capacity to the photovoltaic configuration capacity is 3: 1; meanwhile, energy storage configuration capacity is set in the first power supply configuration scheme, and energy storage time is set to be a fixed value of 4 hours, wherein the initial setting capacity of the energy storage configuration capacity is 0. In this embodiment, the thermal power configuration capacity, the ratio of the wind power configuration capacity to the photovoltaic configuration capacity, and the energy storage configuration capacity configured in the first power configuration scheme are a first parameter set in the first power configuration scheme.
In this embodiment, the first power configuration scheme with the set first parameter set is input into the new energy delivery base simulation model for simulation operation, and the new energy occupation ratio and the new energy comprehensive power rejection rate of the first power configuration scheme during the simulation operation of the new energy delivery base simulation model are calculated according to the relevant data of the first parameter set in the first power configuration scheme and extracted by the production simulation software.
In this embodiment, the calculated new energy ratio is compared with a preset threshold corresponding to the new energy ratio, whether the new energy ratio is higher than the preset threshold corresponding to the new energy ratio is determined, and meanwhile, the calculated new energy comprehensive power rejection ratio is compared with a corresponding preset threshold, and whether the new energy comprehensive power rejection ratio is lower than the preset threshold corresponding to the new energy comprehensive power rejection ratio is determined. As a preferable scheme in this embodiment, the preset threshold corresponding to the new energy occupation ratio is set to be 50%, and the preset threshold corresponding to the comprehensive power abandonment rate of the new energy is set to be 7%.
In this embodiment, when the calculated new energy ratio and the new energy comprehensive power abandonment rate simultaneously satisfy the corresponding preset threshold, that is, the calculated new energy ratio is higher than 50%, and the calculated new energy comprehensive power abandonment rate is lower than 7%, it is determined that the corresponding preset threshold is satisfied.
In this embodiment, when the calculated new energy ratio and the new energy comprehensive power abandonment rate cannot simultaneously satisfy the corresponding preset threshold values, it is determined that the corresponding preset threshold values are not satisfied, that is, when the calculated new energy ratio is not higher than 50% and the calculated new energy comprehensive power abandonment rate is not lower than 7%, it is determined that the corresponding preset threshold values are not satisfied; or when the calculated new energy ratio is higher than 50% but the calculated new energy comprehensive power abandonment rate is not lower than 7%, determining that the corresponding preset threshold value is not met, or when the calculated new energy comprehensive power abandonment rate is lower than 7% but the calculated new energy ratio is not higher than 50%, determining that the corresponding preset threshold value is not met.
Step 103: and when the situation that the corresponding preset threshold value is not met is determined, updating the first power supply configuration scheme according to a preset rule, and returning to the step of judging whether the new energy occupation ratio and the new energy comprehensive power abandon rate of the first power supply configuration scheme in the simulation operation of the new energy delivery base simulation model meet the corresponding preset threshold value or not until the situation that the corresponding preset threshold value is met is judged.
In this embodiment, when it is determined that the corresponding preset threshold is not satisfied, the first parameter set in the first power configuration scheme is updated according to a preset rule. As an example in this embodiment, when it is determined that the corresponding preset threshold is not met, updating a first parameter set in the first power configuration scheme according to a first preset rule, increasing the energy storage configuration capacity of the first parameter set in the first power configuration scheme, and updating the first power configuration scheme with the increased energy storage configuration capacity; and returning to step 102 to judge whether the new energy ratio and the new energy comprehensive power curtailment rate of the first power supply configuration scheme during the simulation operation of the new energy delivery base simulation model meet corresponding preset thresholds; until the energy storage configuration capacity in the updated first power supply configuration scheme reaches a first preset parameter.
As an example in this embodiment, when it is determined that the corresponding preset threshold is not met, and the energy storage configuration capacity in the first power configuration scheme reaches the first preset parameter, the first parameter set in the first power configuration scheme is updated according to the second preset rule, the ratio of the wind power configuration capacity to the photovoltaic configuration capacity is reduced, the current energy storage configuration capacity in the first power configuration scheme is updated to the initial setting capacity, and the current first power configuration scheme is updated according to the reduced ratio of the wind power configuration capacity to the photovoltaic configuration capacity and the updated energy storage configuration capacity as the initial setting capacity, and the step 102 is returned to "determine whether the new energy occupancy and the new energy comprehensive power dump rate of the first power configuration scheme during the simulation operation of the new energy delivery base simulation model meet the corresponding preset threshold"; and until the ratio of the wind power configuration capacity to the photovoltaic configuration capacity in the updated first power configuration scheme reaches a second preset parameter.
As an example in this embodiment, when it is determined that the corresponding preset threshold is not satisfied, and the energy storage configuration capacity in the first power supply configuration scheme reaches the first preset parameter, and the ratio of the wind power configuration capacity to the photovoltaic configuration capacity in the first power supply configuration scheme reaches the second preset parameter, updating the first parameter set in the first power supply configuration scheme according to a third preset rule, increasing the thermal power configuration capacity, updating the current energy storage configuration capacity in the first power supply configuration scheme to initial set capacity, setting the ratio of the current wind power configuration capacity to the photovoltaic configuration capacity in the first power supply configuration scheme to be initial ratio, and updating the current first power supply configuration scheme according to the increased thermal power configuration capacity, the energy storage configuration capacity updated to the initial set capacity and the ratio of the wind power configuration capacity to the photovoltaic configuration capacity updated to the initial ratio. And returning to step 102 to judge whether the new energy ratio and the new energy comprehensive power curtailment rate of the first power supply configuration scheme during the simulation operation of the new energy delivery base simulation model meet corresponding preset thresholds; and until the ratio of the wind power configuration capacity to the photovoltaic configuration capacity in the updated first power configuration scheme reaches a third preset parameter.
As a preferred scheme in this embodiment, the first preset rule is to increase the energy storage configuration capacity in a sequential stacking manner with 50 as a target number, where a first preset parameter of the energy storage configuration capacity is 300, and a unit is ten thousand kilowatt-hours; the second preset rule is that the ratio of the wind power configuration capacity to the photovoltaic configuration capacity in the ratio of the wind power configuration capacity to the photovoltaic configuration capacity is reduced in a sequential superposition mode by taking 0.5 as a target number, wherein a second preset parameter of the ratio of the wind power configuration capacity to the photovoltaic configuration capacity is 1: 1; the third preset rule is that 100 is taken as a target number, thermal power configuration capacity is increased in a sequential overlapping mode, wherein the third preset parameter of the thermal power configuration capacity is 800, the unit is ten thousand kilowatts, the third preset parameter of the thermal power configuration capacity is set to 800, based on the fact that the new energy delivery project is required to meet the condition that the channel new energy electric quantity accounts for more than 50%, when the delivery end thermal power capacity exceeds 800 ten thousand kilowatts, the installed capacity of the new energy required to be matched is increased to a point that the installed capacity of the new energy does not accord with the new energy technology development amount of the delivery end area, and the operation stability of the power system can be further improved when the delivery scheme of the new energy base is implemented.
Step 104: and when the current first power supply configuration scheme meets the corresponding preset threshold value, calculating the receiving end-to-grid power price of the current first power supply configuration scheme, and storing the current first power supply configuration scheme and the corresponding receiving end-to-grid power price thereof into a scheme alternative set.
In this embodiment, when it is determined that the corresponding preset threshold is met, the receiving-end-to-grid electricity price of the first power supply configuration scheme currently meeting the corresponding preset threshold is calculated by the electricity price measuring and calculating system, and the receiving-end-to-grid electricity price obtained through calculation and the current first power supply configuration scheme corresponding to the receiving-end-to-grid electricity price are stored in the scheme alternative set. In the embodiment, the construction investment amount, the input voltage level, the transmission capacity, the conductor type selection, the line length, the utilization hours, the power transformation (current conversion) and the line static investment of wind power, photovoltaic power, thermal power and energy storage per kilowatt are used as calculation parameters of a power price measuring and calculating system and used for calculating the power price from the receiving end to the grid, wherein the power price from the receiving end to the grid comprises the comprehensive internet power price, the alternating current power price and the direct current power price of a power base at the transmitting end.
Step 105: and judging whether the first parameter set in the current first power supply configuration scheme meets a preset parameter set.
In this embodiment, it is determined whether the energy storage configuration capacity of the current first power configuration scheme reaches a first preset parameter in a preset parameter set; when the energy storage configuration capacity does not reach a first preset parameter, determining that the first parameter set does not meet the preset parameter set, and when the energy storage configuration capacity reaches the first preset parameter, judging whether the ratio of the wind power configuration capacity and the photovoltaic configuration capacity of the current first power supply configuration scheme reaches a second preset parameter in the preset parameter set; when the ratio of the wind power configuration capacity to the photovoltaic configuration capacity does not reach a second preset parameter, determining that the first parameter set does not meet the preset parameter set, and when the ratio of the wind power configuration capacity to the photovoltaic configuration capacity reaches the second preset parameter, judging whether the thermal power configuration capacity of the current first power supply configuration scheme reaches a third preset parameter in the preset parameter set; and when the thermal power configuration capacity does not reach a third preset parameter, determining that the first parameter set does not meet the preset parameter set, and when the thermal power configuration capacity reaches the third preset parameter, determining that the first parameter set meets the preset parameter set.
As a preferred scheme in this embodiment, a first preset parameter in a preset parameter set corresponding to the energy storage configuration capacity of the current first power supply configuration scheme is 300, and the unit of the first preset parameter is ten thousand kilowatts; the second preset parameter in the preset parameter set corresponding to the proportion of the wind power configuration capacity to the photovoltaic configuration capacity of the current first power configuration scheme is 1: 1; the third preset parameter in the preset parameter set corresponding to the thermal power configuration capacity of the current first power supply configuration scheme is 800, and the unit of the third preset parameter is ten thousand kilowatts.
Step 106: and when the preset parameter set is determined not to be met, updating the current first power supply configuration scheme according to a preset rule, and returning to the step of judging whether the new energy occupation ratio and the new energy comprehensive power abandon rate of the first power supply configuration scheme during the simulation operation of the new energy delivery base simulation model meet corresponding preset thresholds or not.
