[0002] There are different types of market participants in the electricity market. When it comes to meeting the balance of the power system, market participants can be mainly divided into two categories: the first category is conventional energy sources, mainly thermal power, which are not limited by the amount of electricity and the regulation time; the second category is new regulation resources, such as energy storage, flexible loads, electric vehicles, and virtual power plants. Although they have good regulation capabilities, they are generally limited by the amount of electricity and the regulation time.
[0003] If resources are not allocated properly, there is a risk of over-reliance on Category II resources, leading to power limitations for those resources. Meanwhile, the power output of Category I resources may fail to achieve system balance due to ramp-up constraints, resulting in wind and solar power curtailment or load shedding. Please refer to [link / reference]. Figure 1 As shown, if the ratio of the first type of regulating resources and the second type of regulating resources is not properly scheduled, the shaded line indicates that the energy provided by the second type of regulating resources will lead to wind and solar power curtailment or load shedding because the power of the second type of regulating resources is exhausted and the ramp-up rate of the first type of regulating resources is not in place.

[0051] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0052] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.
[0053] Example 1
[0054] For Category I regulating resources with relatively low ramp-up rates, effective coordination with Category II market players is needed to improve their ramp-up capabilities. The basis for Category II regulating resources to improve the ramp-up rate of Category I regulating resources is to utilize their ramp-up capabilities until conventional units can catch up to the new power point, such as... Figure 2 As shown. The thin slanted shading line represents the energy provided by the second type of regulating resource, and the thick black solid line represents the operation of the first type of regulating resource. Three factors limit the equivalent ramp rate: 1) the available energy that the second type of regulating resource can charge or discharge; 2) the maximum power that the second type of regulating resource can provide; 3) the power generation limit of the first type of regulating resource. The constraint caused by the energy capacity of the second type of regulating resource can be expressed by equation (1), which means that the area of the thin slanted triangle is less than the sum of the available energy of the second type of regulating resource, and gives the corresponding maximum ramp rate:
[0055] (T end -T start )×R first ×T end / 2≤E sec (1)
[0056]
[0057] In the formula, T end and T start R indicates the start and end times of a transaction. first R second E represents the rate of power change of the first type of regulating resource and the second type of regulating resource. sec This indicates the energy limit for the second type of regulatory resource.
[0058] Meanwhile, Equation (3) shows the limiting results of the power output of the second type of regulating resource and the corresponding maximum ramp rate. This indicates that the power provided by the second type of regulating resource should never exceed its maximum power output limit.
[0059] R second ≤P second,max / T start +R first (3)
[0060] In the formula, P second,max This indicates the maximum power of the second type of regulating resource.
[0061] Furthermore, the constraint arising from the maximum power generation limit is calculated in equation (4). Due to the energy capacity limitation of the second type of regulating resource, the final equivalent output should not exceed the maximum output of the first type of regulating resource.
[0062] R second ≤(P first,max -p first ) / T start (4)
[0063] Therefore, the ramp rate of the second type of regulating resource is limited by equations (1) to (4) to obtain the power of the first and second types of resources at each time.
[0064] therefore:
[0065]
[0066] For the second type of regulatory resource, although it provides less electricity and needs to be charged to obtain electricity later, if only the electricity it provides is considered, the benefits it obtains are low, which is not enough to incentivize the development of flexible regulatory resources. Therefore, a method that considers the value component of ramp-up capacity is proposed.
[0067] When the energy stored in a Type II regulating resource is insufficient, it will be unable to supply power, similar to the fuel reserves in a conventional thermal generator. However, the fuel reserves of a conventional generator are usually sufficient to power it for extended periods, while a typical amount of stored energy may only power a Type II regulating resource for a limited number of hours. Therefore, the stored energy of a Type II regulating resource is a crucial factor determining its availability. In addition to the stored energy during peak hours, the length T of the peak hour is also a factor. peak This is also an important factor in calculating its capacity value. The ramp-up capability (p) of conventional units... s and net load variation power p d The difference between the two types of resources is used to analyze the ramp-up value of the second type: when the net load change rate is less than the ramp-up rate of conventional units, no ramp-up capacity compensation is needed for the second type of resource; when the net load change rate is higher than the ramp-up rate of conventional units, the capacity value of the second type of resource is used as its value component. Throughout the peak period, the i-th flexible resource provides E... i The amount of electricity. Therefore, this invention proposes the following capacity value coefficient during the peak demand period of the system:
[0068]
[0069] The evaluation result of the ramp capacity value component of the i-th flexible resource is as follows:
[0070] ω i =βP cap,i α i (7)
[0071] In the formula, β is the capacity compensation value coefficient, and P cap,i The installed capacity of flexible resource i in the second category of adjustment resources.
[0072] Example 2
[0073] Please see Figure 3 As shown, this invention provides a method for clearing out different market participants considering electricity constraints, allocating regulatory resources to a first type of regulatory resource and a second type of regulatory resource; the first type of regulatory resource is thermal power; the second type of regulatory resource is one or more of energy storage, flexible loads, electric vehicles, and virtual power plants; the method specifically includes the following steps:
[0074] S1. Receive the electricity market clearing request and request the electricity market clearing process;
[0075] At time S2 and T0, the load deviation P of the new energy output is obtained. n and the start time T of the load deviation start and the end time T end ;
[0076] At times S3 and T0, the first type of regulation resource is controlled to perform power ramp-up, and the power change rate of the first type of regulation resource is R. first ;T i At time t, the power regulation amount of the first type of regulation resource is P. first,i =R first *(T i -T0); The power regulation amount of the second type of regulation resource is used to compensate for the power deficiency of the first type of regulation resource. The power regulation amount of the second type of regulation resource is: P second,i =P n -P first,i Under the constraints, the clearing results for the first and second types of regulating resources are obtained by solving the problem; where T0 < T start ;T start ≤T i ≤T end .
[0077] S4. Output the clearing results of the first type of adjustment resources and the second type of adjustment resources.
[0078] like Figure 2 As shown, the thin shaded diagonal line represents the energy provided by the second type of regulating resource, and the thick black solid line represents the operation of the first type of regulating resource. Three factors limit the equivalent ramp rate:
[0079] 1) The second type of regulatory resource is the available energy that can be charged or discharged;
[0080] 2) The maximum power that the second type of regulating resource can provide;
[0081] 3) The power generation limit of the first type of regulating resources.
[0082] The constraint caused by the energy capacity of the second type of regulating resources can be expressed by equation (1), which means that the area of the thin-slanted triangle is less than the total available energy of the second type of regulating resources, and gives the corresponding maximum ramp rate:
[0083] (T end -T start )×R first ×T end / 2≤E sec (1)
[0084]
[0085] In the formula, T end and T start R indicates the start and end times of a transaction. first R second E represents the rate of power change of the first type of regulating resource and the second type of regulating resource. secThis indicates the energy limit for the second type of regulatory resource.
[0086] Meanwhile, Equation (3) shows the limiting results of the power output of the second type of regulating resource and the corresponding maximum ramp rate. This indicates that the power provided by the second type of regulating resource should never exceed its maximum power output limit.
[0087] R second ≤P second,max / T start +R first (3)
[0088] In the formula, P second,max This indicates the maximum power of the second type of regulating resource.
[0089] Furthermore, the constraint arising from the maximum power generation limit is calculated in equation (4). Due to the energy capacity limitation of the second type of regulating resource, the final equivalent output should not exceed the maximum output of the first type of regulating resource.
[0090] R second ≤(P first,max -p first ) / T start (4)
[0091] Therefore, the ramp rate of the second type of regulating resource is limited by equations (1) to (4) to obtain the power of the first and second types of resources at each time.
[0092] therefore:
[0093]
[0094] Example 3
[0095] Please see Figure 4 As shown, this invention provides a clearing device for different market participants considering electricity constraints, allocating regulatory resources to a first type of regulatory resource and a second type of regulatory resource; the first type of regulatory resource is thermal power; the second type of regulatory resource is one or more of energy storage, flexible load, electric vehicles, and virtual power plants; including:
[0096] The receiving module is used to receive electricity market clearing requests and request electricity market clearing.
[0097] The data acquisition module is used to obtain the load deviation P of the new energy output at time T0. n and the start time T of the load deviation start and the end time T end ;
[0098] The control module is used to control the first type of regulating resource to perform power ramping at time T0, where the power change rate of the first type of regulating resource is R.first ;T i At time t, the power regulation amount of the first type of regulation resource is P. first,i =R first *(T i -T0); The power regulation amount of the second type of regulation resource is used to compensate for the power deficiency of the first type of regulation resource. The power regulation amount of the second type of regulation resource is: P second,i =P n -P first,i Under the constraints, the clearing results for the first and second types of regulating resources are obtained by solving the problem; where T0 < T start ;T start ≤T i ≤T end .
[0099] The output module is used to output the clearing results of the first type of adjustment resources and the second type of adjustment resources.
[0100] like Figure 2 As shown, the thin shaded diagonal line represents the energy provided by the second type of regulating resource, and the thick black solid line represents the operation of the first type of regulating resource. Three factors limit the equivalent ramp rate:
[0101] 1) The second type of regulatory resource is the available energy that can be charged or discharged;
[0102] 2) The maximum power that the second type of regulating resource can provide;
[0103] 3) The power generation limit of the first type of regulating resources.
[0104] The constraint caused by the energy capacity of the second type of regulating resources can be expressed by equation (1), which means that the area of the thin-slanted triangle is less than the total available energy of the second type of regulating resources, and gives the corresponding maximum ramp rate:
[0105] (T end -T start )×R first ×T end / 2≤E sec (1)
[0106]
[0107] In the formula, T end and T start R indicates the start and end times of a transaction. first R second E represents the rate of power change of the first type of regulating resource and the second type of regulating resource. sec This indicates the energy limit for the second type of regulatory resource.
[0108] Meanwhile, Equation (3) shows the limiting results of the power output of the second type of regulating resource and the corresponding maximum ramp rate. This indicates that the power provided by the second type of regulating resource should never exceed its maximum power output limit.
[0109] R second ≤P second,max / T start +R first (3)
[0110] In the formula, P second,max This indicates the maximum power of the second type of regulating resource.
[0111] Furthermore, the constraint arising from the maximum power generation limit is calculated in equation (4). Due to the energy capacity limitation of the second type of regulating resource, the final equivalent output should not exceed the maximum output of the first type of regulating resource.
[0112] R second ≤(P first,max -p first ) / T start (4)
[0113] Therefore, the ramp rate of the second type of regulating resource is limited by equations (1) to (4), and the clearing results of the first type of regulating resource and the second type of regulating resource (power of the first type of resource and the second type of resource at each time) are obtained by solving the equations (1) to (4).
[0114] therefore:
