Description

New energy matching and storing frequency modulation method and system
Technical Field
The invention relates to the technical field of new energy matched storage frequency modulation, in particular to a new energy matched storage frequency modulation method and a system.
Background
At present, along with the rapid increase of the installed capacity and the generated energy of the new energy power generation grid connection, the proportion of the installed capacity to the installed capacity of various power sources in China is higher and higher, the new energy power generation has the characteristics of randomness, intermittence and the like, and when the large-scale new energy power generation grid connection is performed, the total inertia of the power system is rapidly reduced, so that the serious problem of the frequency stability of the power system is caused: firstly, renewable energy units generally do not have or have lower inertial response capabilities, and replacement of the renewable energy units by conventional energy units will reduce the inertia of the power system; secondly, the improvement of the renewable energy permeability reduces the number of the traditional power sources with better controllability as standby power sources, and if the control strategy of the traditional power system is still used, the system frequency deviation is increased obviously.
The power generation principle of wind power and photovoltaic is different from that of a traditional power supply, and the power generation principle is different from that of a traditional power supply, so that no rotational inertia is supported when the power grid frequency and voltage fluctuation are handled, and the transient stability of the power grid is reduced. In order to ensure the stability of high-proportion new energy to be accessed into a power grid, the participation of the new energy in maintaining the stability of the frequency of the power grid is urgently needed. Currently, two main ways of new energy participation in maintaining the stability of the power grid frequency are: firstly, an AGC (automatic power generation control) mode is adopted, a dispatching center issues a command to a fan/photovoltaic inverter, the output completion time is about 1min, the mode can only participate in secondary frequency modulation of a power system, and the transient stability of the power grid frequency cannot be maintained; and secondly, adding a primary frequency modulation device in a new energy power station reconstruction mode, wherein the primary frequency modulation device adjusts the active output of the new energy power station according to the system frequency, participates in primary frequency modulation control of a power system, and loses the stability of the power grid frequency until the output completion time of a fan/photovoltaic inverter is about 15s.
The primary frequency modulation function of the new energy power station requires to keep a certain active standby fast adjustment power to meet the requirement of grid frequency stabilization, the loss of the power on the internet can be caused, and the safety accident of the generator set can be caused. The diameter of the impeller of the modern large-scale wind turbine generator is generally up to hundred meters, mechanical faults are easy to occur due to complex working conditions, equipment is expensive, and the cost can be recovered after stable operation for 6-8 years (the design service life is generally 20 years). Mechanical failure is mainly caused by excessive fatigue load accumulation, and the occurrence of mechanical failure of key components such as blades, a transmission chain, a tower and the like can not only cause shutdown, but also possibly cause tower falling, and even cause serious safety accidents. Therefore, primary frequency modulation load shedding control of the wind turbine generator is particularly important, and if the fatigue load in the running process of the wind turbine generator cannot be reduced, the power generation loss and the operation and maintenance cost can be increased.
The virtual power plant organically combines distributed power generation, energy storage and flexible load, integrates response resources through matched regulation and communication technologies, and realizes aggregation and coordination control of controllable source load storage resources at the demand side, so that a special power plant is formed to participate in the power market and the power grid operation.
Along with the acceleration of the construction of a novel power system taking new energy as a main body, the novel power system is combined with the perception and prediction of the running situation of a power grid under the scene of accessing large-scale new energy into the power system, plays the role of realizing active support by rapid power control of large-scale new energy, energy storage and flexible load, has great significance for safe and stable running of the power system, and is in an outstanding stage in related research, so that the novel power system has wide development prospect.

acquiring a new energy allocation and storage frequency modulation response mechanism input by a worker;
or alternatively, the first and second heat exchangers may be,
establishing a new energy allocation and storage frequency modulation response mechanism expert discussion room;
acquiring a plurality of discussion information in a new energy allocation and storage frequency modulation response mechanism expert discussion room; the discussion information includes: a voice conversation record and a text conversation record;
based on a plurality of discussion information, a new energy allocation and storage frequency modulation response mechanism is established;
or alternatively, the first and second heat exchangers may be,
acquiring establishment basis information from a big data platform; the establishment basis information comprises: a new energy allocation and storage frequency modulation response mechanism and a dynamic effect value of the other new energy allocation and storage modules which are in one-to-one correspondence;
and establishing a new energy allocation and storage frequency modulation response mechanism based on the establishment basis information.
The working principle and the beneficial effects of the technical scheme are as follows:
the new energy is matched with the mode of establishing the frequency modulation response mechanism to store three kinds of: 1. is directly input by the staff. 2. And establishing a new energy allocation and storage frequency modulation response mechanism expert discussion room, similar to an online conference room, accessing each expert into the discussion room, jointly discussing and formulating a new energy allocation and storage frequency modulation response mechanism, and after the discussion is finished, establishing the new energy allocation and storage frequency modulation response mechanism based on a plurality of discussion information generated by the discussion of the experts in the discussion room. 3. The big data platform is responsible for collecting new energy allocation and storage frequency modulation response mechanisms and dynamic effect values of other new energy allocation and storage modules, and establishing the new energy allocation and storage frequency modulation response mechanisms according to the new energy allocation and storage frequency modulation response mechanisms; the dynamic effect value reflects the effect of the new energy allocation and storage frequency modulation response mechanism of the new energy allocation and storage module after the new energy allocation and storage module is put into use. Three modes are introduced to establish a frequency modulation response mechanism of new energy allocation and storage, so that the applicability of the system is greatly improved.
In one embodiment, based on a plurality of discussion information, establishing a new energy allocation and storage frequency modulation response mechanism comprises:
semantic extraction is carried out on the discussion information to obtain first speaking semantics;
establishing a time axis;
acquiring the generation time of discussion information;
setting a first utterance sense on a timeline based on a generation time;
traversing the first speaking semantics sequentially from beginning to end on the time axis, each time of traversing, matching the traversed first speaking semantics with second speaking semantics in a preset effective discussion semantics library, and if the matching is met, acquiring a preset ambiguity semantics library and a first sub-response mechanism corresponding to the matched second speaking semantics;
matching the first speaking semantics in a preset time range after the traversed first speaking semantics on the time axis with the third speaking semantics in the ambiguity semantic library;
if the two sub-response mechanisms are not matched, the first sub-response mechanism is used as a response mechanism to be combined;
otherwise, the first speaking meaning matched with the matching is used as a fourth speaking meaning;
acquiring a preset second sub-response mechanism corresponding to third speaking semantics matched and conforming to last fourth speaking semantics on a time axis, and taking the second sub-response mechanism as a response mechanism to be combined;
and after traversing the first speech meaning, combining each response mechanism to be combined to obtain a new energy allocation and storage frequency modulation response mechanism.
The working principle and the beneficial effects of the technical scheme are as follows:
based on the semantic extraction technology, the first speaking semantics of the discussion information are extracted. The first speech meaning is set on a time axis according to the generation time of the discussion information from which the first speech meaning originates, and when the first speech meaning is set, the generation time corresponds to the time point on the time axis one by one. The preset effective discussion semantic library comprises a second speaking semantic for a plurality of reaction experts to make new energy allocation and storage frequency modulation response mechanism discussion decisions, for example: the "dead zone range is set to 49.95-50.05 Hz", etc. Traversing the first speaking semantics from head to tail (according to time sequence) on a time axis, matching the first speaking semantics with any second speaking semantics, and if the matching is met, explaining that an expert starts to make a new energy allocation and storage frequency modulation response mechanism discussion decision. The preset ambiguity semantic library corresponding to the matched second speech semantics includes third speech semantics of the divergence opinion from the viewpoint of the matched second speech semantics, for example: the second speech meaning matched with the matching is that the dead zone range is set to be 49.95-50.05 Hz, and the third speech meaning is that the dead zone range is set to be 49.96-50.03 Hz bar. The first sub-response mechanism is a decision result corresponding to the matched second speech semantics, for example: the matching and conforming second speaking semantics are that the dead zone range is set to be 49.95-50.05 Hz, and the first sub-response mechanism is that the dead zone range is set to be 49.95-50.05 Hz. The preset time range is specifically, for example: 30 seconds. And matching the first speaking semantics in a preset time range after the traversed first speaking semantics on the time axis with the third speaking semantics in the ambiguity semantic library. If the matching is not consistent, the first sub-response mechanism is used as the response mechanism to be combined, which indicates that no other expert holds different comments. If the matching is met, the expert holds different comments. In general, when different opinions are held, the generation of the different opinions is a discussion process, and the final different opinions are discussion results, so that the first speech meaning matched and conforming to the first speech meaning is taken as fourth speech meaning, a preset second sub-response mechanism corresponding to the third speech meaning matched and conforming to the final fourth speech meaning on the time axis is acquired, and the second sub-response mechanism is taken as a response mechanism to be combined. The second sub-response mechanism is the same as the first sub-response mechanism. And after the traversal is finished, combining each response mechanism to be combined to obtain the new energy matched and stored frequency modulation response mechanism.
Generally, when an expert discusses and decides a new energy allocation and storage frequency modulation response mechanism, a person needs to be arranged to conduct discussion recording, the result of each discussion is recorded, and finally summarizing is conducted, so that the new energy allocation and storage frequency modulation response mechanism is determined, and the method is complicated. According to the embodiment of the invention, whether an expert starts to discuss and decide a new energy allocation and storage frequency modulation response mechanism is firstly determined based on semantic recognition, if yes, whether the expert holds different opinions is determined, if yes, the discussion result is determined in a self-adaptive mode, and finally, summarization is carried out, so that convenience is improved, and meanwhile, humanization and intelligence are realized.
In one embodiment, based on the establishment basis information, establishing a new energy allocation and storage frequency modulation response mechanism includes:
acquiring first module information of a new energy allocation and storage module;
acquiring second module information of other new energy allocation and storage modules;
performing information matching on the first module information and the second module information to obtain an information matching condition; the information matching condition comprises: the information types and the matching degrees of the matching modules are corresponding to each other one by one;

if the value is greater than or equal to a preset value threshold, taking the effect value corresponding to the frequency modulation response mechanism of the other new energy allocation and storage modules as a target effect value;
and taking the new energy allocation and storage frequency modulation response mechanism corresponding to the maximum target effect value as the new energy allocation and storage frequency modulation response mechanism of the new energy allocation and storage module.
The working principle and the beneficial effects of the technical scheme are as follows:
and the first module information of the new energy allocation and storage module and the second module information of other new energy allocation and storage modules are the same, and the new energy allocation and storage module is the equipment model, the equipment history operation data, the equipment history faults and the like in the new energy allocation and storage module.

And determining the value degree of the new energy allocation and storage module corresponding to other new energy allocation and storage modules based on the information matching condition, wherein the larger the value degree is, the more the new energy allocation and storage frequency modulation response mechanism corresponding to the other new energy allocation and storage modules can be used as the new energy allocation and storage frequency modulation response mechanism of the new energy allocation and storage module. Therefore, if the value is greater than or equal to the preset value threshold, the new energy allocation and storage frequency modulation response mechanism corresponding to the maximum effect value in the effect values corresponding to the new energy allocation and storage frequency modulation response mechanisms of the other new energy allocation and storage modules is used as the new energy allocation and storage frequency modulation response mechanism of the new energy allocation and storage module.
Based on the establishment basis information, whether other new energy allocation and storage frequency modulation response mechanisms are similar to the new energy allocation and storage modules or not is considered when the new energy allocation and storage frequency modulation response mechanism is established, and only when the new energy allocation and storage frequency modulation response mechanism corresponding to the other new energy allocation and storage modules is similar enough, the new energy allocation and storage frequency modulation response mechanism corresponding to the other new energy allocation and storage modules can be used for reference.

The working principle and the beneficial effects of the technical scheme are as follows:
based on the information matching condition, there are two ways to determine the value of the corresponding other new energy allocation and storage modules: 1. the value degree determining model is a logic record (generally, the higher the matching degree of some more important information types is, the higher the value degree is, for example, the equipment model is directly dependent on whether equipment is similar or not, so the higher the matching degree of the equipment model is, the higher the reference value is) for determining the value degree of other new energy distribution and storage modules by utilizing a large number of manual works based on the information matching condition, and the value degree determining model is an artificial intelligent model which is obtained after training the neural network model until convergence and can replace the manual work to determine the value degree of other new energy distribution and storage modules based on the information matching condition. 2.

The method and the system are introduced to determine the value corresponding to other new energy allocation and storage modules based on the information matching condition, so that the applicability of the system is improved, and in addition, the value determination model and the value determination library are respectively introduced, so that the determination efficiency of the value is improved. The two modes can be alternatively or simultaneously carried out, and when the two modes are carried out simultaneously, the average value of the value degrees obtained by the two modes is taken as the value degree corresponding to other new energy source distribution and storage modules.
