Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, fig. 1 is a schematic flow chart of a method for determining a renewable energy source and thermal power coupling system according to an embodiment of the present application, and the method is applied to the server in fig. 1, for example, and the method includes the following steps:
S101, constructing at least two renewable energy and thermal power coupling systems RETCS according to an electric power application scene.
Alternatively, the power application scenario may be a place with power demand, for example, a school, a hospital, a hotel, or the like.
Further, RETCS may be a system that connects geographically close renewable energy power generation and thermal power generation to a main power system via coupling points. In contrast to conventional BRTGS (Bundle Renewable Energy and Thermal Power Generation Systems, a bundled renewable energy and thermal power generation system), RETCS does not coordinate geographically dispersed power sources through the grid, but rather internally coordinates renewable energy generation and thermal power generation in close geographic locations, that is, RETCS can be an overall control object, and has better controllability compared with BRTGS, so that the problem of power fluctuation of renewable energy power generation can be better solved. In the northeast power grid of China, because the flexible power source in the region is limited, the comprehensive coordination among the short-distance power sources is needed, RETCS is widely implemented, and the practical application value is realized.
Furthermore, the characteristic indexes of RETCS can be selected according to the characteristics of a plurality of thermodynamic units in RETCS in each region, such as scheduling time interval, active power loss estimation, renewable energy and power capacity demand data, power capacity ratio and coordination strategy, and the characteristic indexes of RETCS and the power source are the same, so that a foundation is laid for determining target RETCS later.
It should be further noted that the number of RETCSs may be configured as required, and the number of RETCSs is not limited in the embodiment of the present invention.
S102, determining the coupling coordination schedule of each RETCS according to the index value of each RETCS under the effective index.
Alternatively, the coupling co-schedule may be a value that measures the coupling effect of the RETCSs, which may be the interaction and interaction between RETCSs. The effective index can be an index which can influence RETCS, and the selection of the effective index is based on the thermal power fluctuation rate, the renewable energy source utilization and the whole RETCS so as to comprehensively reflect the coupling effect; the embodiment of the invention takes three effective indexes of resources, economy and environment as examples for illustration, but the types of the effective indexes are not limited. The index value under the effective index may be the value of each effective index of a RETCS, and the index values under the effective indexes of RETCS may be the same or different.
Furthermore, RETCS can be the power generation system that comprises a plurality of power sources, there is coupling effect between a plurality of power sources, and coupling effect receives the influence of factors such as resource, economy, environment. RETCS has common interaction and common characteristics in three aspects of resources, economy and environment. First, the resources in RETCS play an important role in performance improvement. On one hand, RETCS with better resource utilization can improve the utilization rate of renewable energy power generation, reduce the fluctuation of CP, and on the other hand, RETCS with better resource utilization can improve economic benefit and environmental benefit. However, excessive pursuit of resource utilization increases economic costs and is harmful to the environment. Second, the economy in RETCS represents a balance and link between resources and environments. If environmental impact and reasonable utilization of resources are not considered, better economic benefits cannot be obtained. Third, resources and economics are constrained by RETCS environmental performance.
Specifically, after determining the index value of each RETCS under the effective index, the embodiment of the invention averages the index values under the effective indexes, and the obtained average value of each RETCS is the coupling co-schedule of each RETCS.
S103, selecting a target RETCS of the power application scene from the RETCSs according to the coupling coordination schedule of the RETCSs.
Specifically, after determining the coupling co-schedule of each RETCS, the embodiment of the invention sorts the coupling co-schedules of each RETCS, and takes the RETCS with the largest coupling co-schedule in each RETCS as the target RETCS of the power application scene.
In the method for determining the renewable energy and thermal power coupling system, at least two RETCSs are constructed according to the electric power application scene, then the coupling cooperative schedule of each RETCS is determined according to the index value of each RETCS under the effective index, and finally the target RETCS of the electric power application scene is selected from each RETCS according to the coupling cooperative schedule of each RETCS. Compared with the method for determining the renewable energy source and thermal power coupling system in the related art, the method for determining the renewable energy source and thermal power coupling system has the advantages that renewable energy source power generation and thermal power generation close to each other in geographic position are coordinated together to serve as control objects, the power fluctuation problem during power generation can be reduced, the calculation accuracy of coupling co-scheduling of RETCS is improved, and the technical effect of more accurately selecting target RETCS is achieved.
On the basis of the above embodiment, the step of determining the coupling co-schedule of each RETCS is decomposed and refined. Optionally, as shown in fig. 2, the implementation process specifically includes the following steps:
s201, for each RETCS, determining an index value of the RETCS under each effective index according to renewable energy data, thermal power data and system data of the RETCS under each effective index.
Optionally, the renewable energy data, the thermal power data and the system data in the embodiment of the present invention may be specific data set as required for each effective index of a specific RETCS, and the embodiment of the present invention does not limit the type of the specific data.
Specifically, after the renewable energy source data, the thermal power data and the system data of the RETCS under each effective index are obtained, the renewable energy source data, the thermal power data and the system data of the RETCS under each effective index are summed, and the obtained summation result is the index value of the RETCS under each effective index.
S202, determining the coupling coordination schedule of each RETCS according to the index value of each RETCS under each effective index.
Specifically, after determining the index value of each RETCS under each effective index, the embodiment of the invention uses the average value of the index values of each RETCS under each effective index as the coupling co-schedule of the RETCS for each RETCS.
It can be understood that, by introducing the coupling co-schedule in the embodiment of the present invention, the coupling co-schedule of each RETCS can be determined according to the index value of each RETCS under each effective index, so as to lay a foundation for the subsequent determination of the target RETCS.
On the basis of the above embodiment, the step of determining the index value of the RETCS at each effective index is refined. Optionally, as shown in fig. 3, the implementation process specifically includes the following steps:
s301, determining a first value according to the renewable energy source data of the RETCS under the effective index aiming at each effective index.
Optionally, in the embodiment of the invention, the second-level index and the third-level index are set under each effective index (first-level index), so that the coupling coordination degree calculation of RETCS can be refined, and the obtained coupling coordination degree is more accurate; in addition, the secondary indexes under each effective index in the embodiment of the invention are set as renewable energy source data, thermal power data and system data, but the tertiary indexes under each secondary index under each effective index are set according to the type of the effective index, so that the tertiary indexes under each secondary index under the effective index are different. The index system of RETCS is shown in Table 1.
TABLE 1 index System of RETCS
As shown in table 1, the system data under the resource effective index includes the system energy shortage, the coupling power fluctuation rate and the average power adjustment range of RETCS; the thermal power data under the effective indexes of the resources comprise a rapid lifting rate and a rapid adjusting rate; the renewable energy data under the resource availability index includes renewable energy utilization. The system data under the economic and effective index comprises the whole unit generating income of RETCS and the annual usage hours of RETCS; the thermal power data under the economic and effective indexes comprise unit power generation income of the thermodynamic machine set, power generation operation cost of the thermodynamic machine set and annual use hours of the thermodynamic machine set; the renewable energy data under the economic efficiency index includes unit generation income of the renewable energy and annual utilization time of the renewable energy. The system data under the environment effective index comprises the equivalent carbon emission of the total unit power generation life cycle; the thermal power data under the environment effective index comprises the unit power generation pollution cost of the thermodynamic unit; the renewable energy data under the environment effective index comprises the equivalent carbon emission of the renewable energy unit in the power generation life cycle.
Referring now to table 1, the procedure for obtaining the index value of the RETCS at each effective index is as follows:
The three-level index in table 1 needs to be normalized to obtain a normalized value, the normalized value may be used to characterize the score of each tertiary indicator. In a positive index, the higher the index value, the higher the score. In the negative index, the higher the index value, the lower the score can eliminate the influence of different scale units and scales of different RETCSs on the calculation accuracy of the index value under each effective index. The normalized value depends on whether the contribution of the tertiary index to RETCS is positive or negative. Wherein, the contribution of the three-level index to RETCS is positive, and the normalized value isWherein U is ij A j-th tertiary index of the i-th RETCS; x is X ij Is U (U) ij Wherein X is ij ∈[0,1]. When the contribution of the three-level index to RETCS is negative, the normalized value isAfter the normalization processing is performed on the three-level index, the index value of the three-level index under each two-level index can be obtained, as shown in the formula (1).
Wherein Ui is an index value under the ith secondary index, and Ui E [0,1 ]]；λ ij The preset weight value of the j-th three-level index of the i-th RETCS is obtained.
Specifically, in the embodiment of the invention, after determining the renewable energy data of the RETCS under the effective index, the first numerical value corresponding to the renewable energy data of the RETCS under the effective index can be obtained by substituting the renewable energy data into the formula (1).
S302, determining a second value according to the thermal power data of the RETCS under the effective index.
Specifically, in the embodiment of the present invention, after determining the thermal power data of the RETCS under the effective index, the second value corresponding to the thermal power data of the RETCS under the effective index is obtained by substituting the thermal power data of the RETCS into the formula (1).
S303, determining a third numerical value according to the system data of the RETCS under the effective index.
Specifically, after determining the system data of the RETCS under the effective index, the embodiment of the invention substitutes into the formula (1) to obtain a third value corresponding to the system data of the RETCS under the effective index.
S304, taking the sum of the first value, the second value and the third value as an index value of the RETCS under the effective index.
It can be understood that the renewable energy source data, the thermal power data and the system data are introduced in the embodiment of the invention, and the performance parameter values can be analyzed by utilizing the renewable energy source data, the thermal power data and the system data, so that the index value of the RETCS under the effective index is obtained, thereby laying a foundation for the subsequent determination of the target RETCS.
After RETCS is built, RETCS needs to be optimized to improve the coupling effect of RETCS, so that the accuracy of subsequent coupling coordination degree calculation for optimized RETCS is improved.
(1) The uncertainty of the factor affecting RETCS is eliminated.
The power demand and power supply of renewable energy power generation is uncertain due to various factors such as weather and user behavior. Fluctuations in power demand and renewable energy yield caused by these uncertainties will lead to inefficient utilization of renewable energy resources, also reducing the economic benefits of RETCS and increasing environmental costs. These combined effects will result in a reduction of the coupling effect of RETCS and therefore the effect of these uncertainties on RETCS needs to be eliminated to improve the utilization of thermal power by the coupling effect of RETCS. Uncertainty of factors affecting RETCS by using a thermal power method can be adopted in the embodiment of the invention.
(2) Annual total revenue of RETCS is maximized.
For the system operator, RETCS optimization is targeted at maximizing benefit. The generation revenue of multiple thermal units in RETCS is related to the real-time DPR service that it can provide. In the embodiment of the invention, when the average load rate of the starting unit at a certain moment is smaller than the compensation standard, the compensation of the DPR service can be obtained. Therefore, the maximum annual total income obtained finally is shown in the formula (2),
max F A ＝F GI -(F OP，d +F OP，u )-(F TE，d +F TE，u )-F ON，d +F RI， u (2)
wherein F is A Total annual revenue for RETCS; f (F) GI Expected heat unit income for the year; f (F) OP，d 、F OP，u The annual operation cost of the first-stage thermal power generating unit and the second-stage thermal power generating unit are respectively; f (F) TE，d 、F TE，u Respectively is a first and a secondAnnual pollution cost of the thermal power generating unit; f (F) ON，d The annual breaking cost of the thermodynamic machine set is realized; f (F) RI，u Annual revenue for the second stage renewable energy generator set. The above formula consists of two phases: subscript d represents the first stage decision and subscript u represents the second stage decision. The decision in the first stage is deterministic and is made before uncertainty is considered. The decision of the second stage is stochastic, at which stage real-time scheduling resources are utilized to correct the effects of uncertainty after the first stage decision, and the uncertainty is converted to deterministic using the scenario and its corresponding probabilistic representation.
