Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
In order to at least solve the technical problems provided by the invention, the embodiment of the invention provides a method for processing abnormal discharge of an electric power spot market.
Fig. 1 is a schematic flow chart of a method for processing abnormal discharge of a power spot market according to an embodiment of the present invention, referring to fig. 1, the method provided by the embodiment of the present invention may include the following steps:
s11, acquiring abnormal conditions of the target power spot market.
S12, processing the clearing abnormal condition based on the clearing abnormal condition and the preset corresponding relation between the clearing abnormal condition and the processing.
In the embodiment of the invention, a certain electric power spot market can be defined as a target electric power spot market, and the electric power spot market of a certain area can be defined as a target electric power spot market, so that abnormal clearing monitoring of one or more electric power spot markets is realized. The target power spot market is not particularly limited herein.
For example, in a specific implementation process, the clearing abnormal condition may be obtained through a power system connected to the power spot market, or the clearing abnormal condition may be obtained wirelessly through each terminal, which is not limited herein, and the invention is applicable to the protection scope of the invention as long as the clearing abnormal condition can be obtained.
Optionally, acquiring the abnormal condition of the target power spot market may include: acquiring abnormal clearing information of a target electric power spot market; extracting key information in the clear abnormal information based on the prediction rule; acquiring abnormal classification information of clear abnormal information according to the key information, preset key information and abnormal classification corresponding relation; based on the clearing abnormal condition and the corresponding relation between the preset clearing abnormal condition and the processing, the processing of the clearing abnormal condition comprises the following steps: and processing the abnormality clearing condition based on the abnormality classification information and the corresponding relation between the preset abnormality classification information and the processing.
Specifically, when acquiring the abnormality clearing situation, in order to acquire specific information of the abnormality more accurately, the acquired abnormality information may be sorted, for example, key information in the abnormality clearing information may be extracted through technologies such as network and information crawling, and after acquiring the key information, abnormality classification information of the abnormality information may be obtained through a pre-established key information and abnormality classification correspondence.
For example, the acquired abnormal condition of clearing is "typhoon occurred in a level due to influence", and at this time, the key information of the abnormal information of clearing is extracted as "typhoon", and the abnormal classification information corresponding to "typhoon" is obtained as "natural disaster" from the preset key information and abnormal classification correspondence. Thus, according to the exception handling method corresponding to the natural disasters, the exception condition is handled.
Optionally, the anomaly classification information includes: natural disasters; presetting corresponding relation between abnormal classification information and processing, wherein the method comprises the following steps: and at least one of starting up, stopping, temporarily arranging the power transmission and transformation equipment to stop and temporarily stopping power transmission and transformation maintenance and power transmission measures is adopted according to the influence range and degree of the natural disasters.
For example, typhoons, ice disasters, mountain fires, floods, earthquakes and the like can be set as natural disasters, and in order to ensure the life of people in disaster areas and the necessary electricity consumption, the preset corresponding relationship between abnormal classification information and processing can be: according to the range and degree of disaster influence, measures such as starting up, stopping, temporarily arranging power transmission and transformation equipment to stop running, temporarily stopping power transmission and transformation maintenance and recovery power transmission can be adopted. In order to enhance the capability of the power grid for resisting extreme disasters and ensure the safe operation of the power grid, the power dispatching mechanism can set coastal coal-fired units in typhoons influence areas as necessary units according to the operation needs of the system 3 days before and during login of typhoons; the power dispatching mechanism can set coastal gas units in typhoon influence areas as necessary units according to the operation requirement of the system 1 day before and during typhoon logging, so that when fuel supply constraint exists in the gas units in other areas, the corresponding units can be set as necessary units. After typhoon lands, under the condition that the system security risk is controllable, the power dispatching mechanism releases the necessary setting. The power dispatching mechanism can set a machine set which has network support on a disaster influence area or can play a role of ice melting in a matching way as a machine set to be started according to the operation requirement of a system during the period of rain, snow and freezing disaster risk or mountain fire risk validation.
Optionally, the anomaly classification information includes: the negative standby capacity does not meet the standby requirement; presetting corresponding relation between abnormal classification information and processing, wherein the method comprises the following steps: and according to the power balance of the power system and the condition of the safety constraint of the power grid, arranging the generator set to carry out deep peak shaving outside the set which is reserved or cleared in the frequency modulation auxiliary service market.
For example, in a period that the negative standby capacity does not meet the standby requirement in the operation day, the power dispatching mechanism can be set to arrange the generator set to carry out deep peak shaving according to the actual conditions of system power balance and power grid safety constraint besides the set which is pre-cleared or cleared in the frequency modulation auxiliary service market. The deep peak shaver set is used as a fixed output set in the electric energy market and participates in the electric energy market according to relevant regulations. The compensation cost of the depth peak shaving can be set according to the actual situation of the user, and details and limitations are not repeated here.
Optionally, the anomaly classification includes: controlling the power generation condition of the target power plant; presetting corresponding relation between abnormal classification information and processing, wherein the method comprises the following steps: if the control requirement is embodied as electric quantity constraint, keeping the unit of the target power plant to meet the electric quantity constraint requirement when the spot electric energy market is clear in the control period; if the control requirement is embodied as the upper limit requirement or the lower limit requirement of the unit output, the unit is regulated and controlled to meet the output constraint when the spot electric energy market is clear in the control period; if the control requirement is embodied as the unit fixed output, the unit fixed output is regulated within the control period.
For example, in order to realize the regulation and control of the partial areas, a power plant in a certain area can be defined as a target power plant, and the target power plant is regulated and controlled. It should be noted that the target power plant may be a regional power plant or may be a plurality of regional power plants. When the power generation management and control is performed on the target power plant, if the management and control requirement is embodied as electric quantity constraint (such as total consumption amount control and total emission reduction amount control of coal, etc.), the regional unit in the management and control period is set to meet the electric quantity constraint requirement when the spot electric energy market is clear. If the control requirement is embodied as the upper limit or the lower limit of the output of the unit, setting the unit to meet the output constraint at the same time when the spot electric energy market is clear in the control period. If the control requirement is embodied as the set fixed output, the set fixed output is set in the control period, and the market optimization is not participated.
Optionally, the anomaly classification includes: price abnormality; presetting corresponding relation between abnormal classification information and processing, wherein the method comprises the following steps: if the obtained node electricity price is higher than the maximum limit price, the maximum limit price is used for replacing the node electricity price; if the node electricity price is lower than the minimum price, the minimum price is made to replace the node electricity price.
Optionally, presetting the corresponding relation between the abnormal classification information and the processing, and further includes: if the nodes reaching the maximum limit price are more than the first preset number in the preset trading period in the preset time period, setting the spot market price of the same period of the last trading day in the corresponding trading period as the spot market price of the corresponding period; if the nodes reaching the lowest price are more than the second preset number in the preset trading period in the preset time period, the spot market price of the same period of the last trading day is set as the spot market price of the corresponding period in the corresponding trading period.
For example, when a price abnormality occurs, the power transaction mechanism and the power dispatching mechanism can be set to intervene in the spot electric energy market transaction in a price control mode, and corresponding transaction time periods are announced as price control periods.
For example, when the price of electricity at a node from which the market is cleared exceeds the maximum limit, the price of electricity at the node at that transaction period is replaced with the maximum limit. When the electricity price of the node obtained by market clearing is lower than the lowest limit price, the electricity price of the node in the transaction period is replaced by the lowest limit price. The maximum limit price and the minimum limit price of the market comprehensively consider factors such as the operation of power generation enterprises, the electricity price bearing capacity of market users and the like, and the market management committee makes suggestions and executes the suggestions after agreeing with an energy supervision organization and a government department.
For example, the preset time period may be set to 2 hours, the first preset number is set to 50%, and the second preset number is set to 50%, for illustration. In two continuous hours, when 50% or more nodes reach the maximum limit value in 4 trade periods, the spot market price of the same period of the last trade day is used as the spot market price of the corresponding period in the corresponding trade period. In two continuous hours, when 50% or more of the nodes reach the lowest price in 4 trade periods, the spot market price of the same period of the last trade day is used as the spot market price of the corresponding period in the corresponding trade period.
Optionally, when the market clearing indication cannot be completed within the specified time, the spot market price of the same period of the last trade day is used as the spot market price of the corresponding period in the corresponding trade period. When none of the above-mentioned conditions occurs, the price control period is automatically terminated from the next period.
Optionally, the anomaly classification includes: the market clearing result has errors; presetting corresponding relation between abnormal classification information and processing, wherein the method comprises the following steps: carrying out clearing calculation again based on the original boundary condition to obtain a corrected clearing result; judging whether the clearing result is executed or not, and if the clearing result is not executed, executing correction of the clearing result; if the clearing result is executed and the market is not settled, executing correction of the clearing result; if the market is settled, the settlement electric charge is supplemented according to a preset standard.
For example, when the technical support system operates abnormally and the issued market clearing result is wrong, the clearing calculation needs to be carried out again according to the original boundary conditions, the corrected clearing result is obtained, and the corrected clearing result is issued to market members in time. If the result is not executed after recalculating the correction result, the result is executed according to the result after correction. If the result of the correction is recalculated and the result of the clearing is already executed but the market is not formally settled, the result of the correction is settled. If the correction result is recalculated and the market has officially settled, the electric charge is recovered according to the correlation principle of settlement error recovery in the preset standard.
Optionally, in the early-day electric energy market and real-time electric energy market organization link, when the condition of power supply shortage exists in a prediction part period and the condition of starting up the market stop is not reached, the marketized demand side response resource is preferentially called. And if the marketized demand side response resource is expected to be called and the power supply can meet the demand, the load prediction data is adjusted according to the demand side response quantity, and market clearing is carried out according to the adjusted load prediction data. And if the power supply still does not meet the demand after the marketized demand side responds, starting the orderly power utilization scheme according to the relevant regulations until the power supply meets the demand, and carrying out market clearing according to the adjusted load prediction data. The operation rule of the marketized demand side response is formulated separately.
Alternatively, when faced with a severe under-supply situation, government authorities may suspend market transactions in accordance with relevant regulations and procedures, organizing the implementation of orderly power usage schemes. When major natural disasters such as typhoons and earthquakes occur and sudden events affect power supply or grid safety, government departments and energy supervision institutions can suspend market transactions according to relevant regulations and programs to temporarily implement power generation plan management.
The energy authorities may make decisions about stopping the power market with government authorities and publish the cause of the stopping to power market members in one of (1) the power market is not operating and managed according to rules; (2) The power market transaction rules are not adapted to the power market transaction needs and must be modified significantly; (3) The electric power market transaction generates malicious behavior of collusion and market manipulation, and seriously affects the transaction result; (4) Major faults occur in the power market technical support system (including dispatching operation technical support systems, automation systems, data communication systems and the like), so that transactions cannot be performed for a long time; (5) inability to bid for trading due to unreliability; (6) severe anomalies occur in the power market.
When the situation that the market operation mechanism processes accidents and arranges the operation of the power system according to the first safety principle occurs, the market operation mechanism can stop the electric power spot market transaction and report the government and the energy supervision mechanism as soon as possible; (2) When major power supply or grid faults occur, the ordered supply of power or the safe operation of a power system is affected; (3) When the main and standby power grid is switched due to major natural disasters such as typhoons, earthquakes and the like, emergencies and the like; (4) When major faults occur in the power market technical support system (including a dispatching operation technical support system, an automation system, a data communication system and the like), and spot market transactions cannot be normally organized; (5) And when other serious emergency situations affecting the safe operation of the power grid occur.
When the current machine set is started up and combined, the power dispatching mechanism takes the principle of ensuring the orderly supply of power and the safe operation of a power grid as well as comprehensively considering the boundary conditions of operation day system load regulation prediction, class A machine set planning, outsourcing power planning and the like, and compiles a day-ahead power generation dispatching plan for the operation day. The actual execution result of the operation day and the real-time electric energy market price are taken as the daily electric energy market clearing result of the operation day. (2) When the real-time electric energy market is stopped, the real-time electric energy market is not developed in a corresponding period, the electric power dispatching mechanism is used for guaranteeing orderly supply of electric power and guaranteeing the safe operation principle of the power grid on the basis of the current unit starting combination, and the real-time power generation plan of the generator set is adjusted based on the latest power grid operation state and ultra-short-term load prediction information. And taking the real-time electric energy market price of the same time period of the latest trading day as the real-time electric energy market price in the corresponding settlement time period during the period of the market suspension.
When the market is suspended for a long time, settlement is performed according to the mode specified by the government and the energy supervision and management. And when the abnormal situation is relieved, the market operation mechanism resumes the normal operation of the market.
According to the power spot market abnormal clearing processing method, abnormal clearing conditions are arranged, the abnormal clearing preprocessing corresponding relation is established in advance, and therefore after the abnormal clearing conditions of the target power spot market are obtained, the abnormal clearing conditions are processed through the preset corresponding relation, and convenience and rapidness are achieved.
