Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0021] Figure 1 A schematic diagram of the power generation capacity assessment method provided in the embodiments of this disclosure; as shown Figure 1 As shown, a method for assessing power generation capacity includes: Step S1: Obtain the first time series running data and the second time series running data; In this embodiment, the first time-series operational data is used to characterize the system's operational status before the addition of new energy sources, and the second time-series operational data is used to characterize the system's operational status after the addition of new energy sources. The time-series operational data includes, but is not limited to: system load time-series data, conventional unit parameters and output data, new energy unit parameters and output data (such as wind power and photovoltaic), and optional energy storage or demand response data. This data can be obtained through dispatch automation systems, energy management systems (EMS), and historical operational databases; or, in planning and forecasting scenarios, generated through time-series simulation models built based on historical data and meteorological information. By acquiring the two types of time-series operational data before and after the addition of new energy sources, a comparable baseline operational status can be formed, providing a unified data foundation for subsequent evaluation of the impact of new energy sources on the system's power supply capacity under the same reliability conditions. This ensures that subsequent calculations and evaluations are based on real or repeatable time-series operational data, avoiding evaluation biases caused by analysis based solely on static capacity or single-point data, and improving the credibility and engineering feasibility of the evaluation results.

[0022] Step S2: Based on preset reliability indicators, construct a first reliability optimization model and a second reliability optimization model using first time-series running data and second time-series running data, respectively. In this embodiment, the probability of load loss (LOLP) is selected as the preset reliability index. A first reliability optimization model is constructed based on the first time-series operating data to describe the supply and demand balance of the system at each time before the addition of renewable energy. A second reliability optimization model is constructed based on the second time-series operating data to describe the supply and demand balance of the system at each time after the addition of renewable energy. The optimization model sets the load loss amount variable and 0-1 slack variables to characterize whether a load loss event occurs at each time. Operating constraints such as unit output limit, minimum output, and availability can be introduced as needed. By constructing an optimization model with reliability index as constraint or objective, the power supply capacity of the system under different operating states can be uniformly described at the mathematical level, avoiding the ideal premise that the system can fully meet the load. This transforms system reliability assessment from empirical judgment into a calculable and comparable optimization problem, laying the model foundation for the subsequent quantitative calculation of equivalent load capacity and equivalent reliable capacity.

[0023] Step S3: Solve the first reliability optimization model and the second reliability optimization model respectively to obtain the first target reliability and the second target reliability; In this embodiment, the first and second reliability optimization models are solved using strategies such as branch and bound, cutting plane, or heuristic algorithms to obtain the lowest load loss probability achievable by the system before and after the addition of new energy sources. These are used as the first target reliability and the second target reliability, respectively. The first target reliability provides a reliability constraint for evaluating power generation capacity from the perspective of equivalent load-carrying capacity, while the second target reliability provides a reliability constraint for evaluating power generation capacity from the perspective of equivalent reliable capacity.

[0024] Step S4: Calculate the equivalent load-carrying capacity based on the first target reliability. In this embodiment, under the condition of maintaining the first target reliability, and combined with the first time-series operational data, the peak load that the system can guarantee after the addition of new energy is calculated. Since the operating state of the system under a given reliability is not unique, the aforementioned peak load may vary within a range. By calculating the additional peak load capacity that the system can bear after the addition of new energy relative to before the addition, the equivalent load-carrying capacity of the new energy can be obtained. Peak load is a key indicator for measuring the system's power supply capacity. Determining the peak load that the system can bear under a given reliability condition can intuitively reflect the true power supply capacity boundary of the system. The equivalent load-carrying capacity characterizes the value of new energy from the load-side perspective, transforming the complex reliability problem into a comparison problem of peak load levels. This allows the improvement effect of new energy on the system's power supply capacity to be clearly quantified, reflecting that the addition of new energy enables the system to serve more loads without reducing reliability.

[0025] Step S5: Calculate the equivalent reliable capacity based on the second target reliability. In this embodiment, under the condition of maintaining the second target reliability, a system model after removing new energy sources is constructed by combining the second time-series operating data. The ideal conventional unit capacity that needs to be added to the system is then calculated, enabling the system to achieve the same reliability level as the system containing new energy sources, thereby obtaining the equivalent reliable capacity of the new energy sources. Since the operating state of the system under a given reliability is not unique, the aforementioned equivalent reliable capacity may vary within a range. Equivalent reliable capacity, measuring the contribution of new energy sources to system reliability from the perspective of the generation side, is a core indicator in capacity planning and capacity market pricing. It allows the reliability contribution of new energy sources to be expressed in a form that can replace the capacity of conventional units, facilitating a unified comparison with traditional power sources.

[0026] Step S6: Assess the power generation capacity based on the equivalent load capacity or equivalent reliable capacity.

[0027] In this embodiment, using equivalent indicators for power generation capacity assessment avoids relying solely on rough estimates based on installed capacity, thereby improving the reliability of the assessment results. This achieves a closed-loop application from reliability assessment to power generation capacity assessment.

[0028] In some possible implementations, after obtaining the first timing data, the following steps are included: The load sequence in the first time series operation data is normalized to obtain the original peak load and the normalized load sequence.

[0029] In this embodiment, after acquiring the first time-series operational data, the system load sequence is normalized. Specifically, using the maximum load value (i.e., the original peak load) within the corresponding time range of the first time-series operational data as a benchmark, the load value at each moment is proportionalized, so that the normalized load sequence value is limited to a preset range (e.g., 0 to 1). The normalization process can employ maximum value normalization, interval scaling, or other equivalent methods. The absolute values ​​of load vary significantly across different time periods and system scales. Directly using the original load values ​​for reliability calculations and optimization modeling can easily lead to inconsistent model parameter scales, affecting the stability and comparability of the optimization solution. Load normalization eliminates differences in load dimensions and scale, making the load change trend the primary analysis object. This helps improve the numerical stability of the load loss probability model and the peak load optimization model, while facilitating comparative analysis across different systems and time scales, thereby enhancing the versatility and applicability of the method of this invention.

[0030] In some possible implementations, the equivalent load-carrying capacity is calculated based on the first objective reliability, including: Based on the first time-series operational data and the first target reliability, construct the first peak load optimization model and the second peak load optimization model; Solve the first peak load optimization model and the second peak load optimization model respectively to obtain the first peak load and the second peak load; The difference between the first peak load, the second peak load and the original peak load is calculated respectively to obtain the equivalent load-carrying capacity.

[0031] In this embodiment, a peak load optimization model with peak load as the decision variable is constructed based on the first time-series operating data, the original peak load, the normalized load sequence, and the first target reliability. This model solves for the peak load that the system can bear under the constraint of a preset reliability index. Since the operating state of the system under a given reliability is not unique, the aforementioned peak load may vary within an interval, where the upper bound is the first peak load and the lower bound is the second peak load. Subsequently, the differences between the first peak load and the second peak load and the original peak load are calculated to obtain the equivalent load-carrying capacity of the new energy source on the load side.

[0032] In some possible implementations, the equivalent reliable capacity is calculated based on the second objective reliability, including: Based on the second time-series operational data and the second target reliability, construct the first reliable capacity optimization model and the second reliable capacity optimization model; Solve the first reliable capacity optimization model and the second reliable capacity optimization model respectively to obtain the first reliable capacity and the second reliable capacity; Based on the first reliable capacity and the second reliable capacity, an equivalent reliable capacity is obtained.

[0033] In this embodiment, the renewable energy output data is removed from the second time-series operational data to form the time-series operational data after removing renewable energy. Based on this, a system model satisfying the second target reliability condition is constructed, and the ideal conventional unit capacity required to be added to the system under the same reliability conditions is calculated. This capacity value is taken as the equivalent reliable capacity of the renewable energy. Since the system's operating state under a given reliability is not unique, the aforementioned ideal conventional unit capacity may vary within a range, where the lower bound is the first reliable capacity and the upper bound is the second reliable capacity. The core idea of ​​equivalent reliable capacity is to assess how much conventional power capacity renewable energy can replace at the reliability level. By removing renewable energy and compensating for capacity in reverse, an equivalent relationship between renewable energy and conventional units can be mathematically established, allowing the reliability contribution of renewable energy to be quantified in the form of capacity substitution. This facilitates a unified comparison with traditional power sources and is beneficial for capacity planning, capacity market design, and reserve capacity configuration.

[0034] In some possible ways, generating capacity is assessed based on equivalent load-carrying capacity or equivalent reliable capacity, including: The equivalent load-carrying capacity is calculated by summing it with the capacity of conventional units to obtain the power generation capacity. or, The equivalent reliable capacity is calculated as the sum of the capacity of the conventional units to obtain the power generation capacity.

[0035] In this embodiment, equivalent load capacity or equivalent reliable capacity is selected as the input indicator based on the application scenario. When using equivalent load capacity, it is superimposed on the total capacity of the normally operating conventional units in the system to obtain the system's power generation capacity from the load side perspective. When using equivalent reliable capacity, it is superimposed on the total capacity of the conventional units to obtain the system's power generation capacity from the generation side perspective. Equivalent load capacity and equivalent reliable capacity reflect the reliability contribution of new energy sources from different technical perspectives, respectively. By combining the calculation with the capacity of conventional units, the reliable power generation capacity of the entire multi-energy complementary system is obtained, improving the accuracy and reliability of the power generation capacity assessment results and making the assessment results more consistent with the actual system situation.

[0036] In some possible implementation methods, reliability metrics are set, including: Calculate the load loss at each moment; Reliability indicators are obtained by statistically analyzing load loss.

[0037] In this embodiment, the system's load loss is calculated at each moment, which is the difference between the system load and the available power generation output. When the power generation output is less than the load, the load loss is recorded; when the power generation output is greater than or equal to the load, the load loss is zero. By statistically analyzing load loss events at multiple moments or under multiple scenarios, the load loss probability is calculated as a reliability indicator. This gives the reliability assessment clear statistical significance, objectively reflects the power supply risk of the system under different operating conditions, and provides a unified reliability benchmark for calculating equivalent load capacity and equivalent reliable capacity.

[0038] Among some possible implementation methods, power generation capacity assessment based on equivalent load capacity includes: The equivalent load-carrying capacity of the new energy source is obtained by calculating the difference in load levels that the power generation system can supply before and after the addition of new energy sources under certain reliability conditions. This leads to the reliable power generation capacity of the multi-energy complementary system from the load-side perspective. In actual calculations, the load level that the system can supply is measured by the peak value of the load curve, and the reliability calculation index... Then, the load shedding probability is used. The power generation capacity assessment method based on equivalent load capacity follows these steps: Before the addition of new energy sources, the system is in constant motion. The original load Normalize the load, and denote the normalized load as... .

[0039] Solve for the load failure probability of the system before the addition of new energy sources. The solution can be obtained through the following optimization model:

Indicates time The actual power generation of the system is less than the system load; The number of time points to be considered in the calculation; .

[0046] The probability of load failure is calculated as follows: Lower limit of the load capacity of new energy sources:

Therefore, the reliable power generation capacity of the multi-energy complementary system at the load side angle is: , In the formula It is the capacity of conventional generating units that can operate normally in a multi-energy complementary system.

[0048] Among the possible implementation methods, power generation capacity assessment based on equivalent reliable capacity includes: By solving for the ideal conventional generating unit capacity that new energy can replace under certain reliability conditions, the equivalent reliable capacity of new energy is obtained, and thus the reliable power generation capacity of the multi-energy complementary system from the power generation side is obtained. In actual calculations, the ideal conventional generating unit capacity that new energy can replace is used... This indicates that reliability calculation indicators The probability of load shedding is still used. The power generation capacity assessment method based on equivalent reliable capacity follows these steps: Solve for the load failure probability of a multi-energy complementary system containing new energy sources. The solution can be obtained through the following optimization model:

[0049] In the formula, This indicates the time of conventional generating units (such as hydropower, thermal power, etc.) contribution; This indicates that the new energy unit is at any time contribution; Indicates time The system load value; It is a moment Loss of load; It is a 0-1 slack variable.

Indicates time The actual power generation of the system is less than the system load; The number of time points to consider during the calculation.
