Meanwhile, the electricity selling business is opened to the social capital, and the market main body is cultivated in multiple ways. In the future, various forms of subjects including power grid companies, power selling companies, load aggregators, energy saving service companies and the like participate in implementing demand response. Encourages the electricity selling main body to provide value-added services including contract energy management, comprehensive energy conservation, energy utilization consultation and the like for the user; the user can voluntarily select to sign a demand response contract with the power grid enterprise, and corresponding economic compensation is obtained according to the contribution. Most users in China can only passively receive simple electricity settlement service at present, and if electricity products and service contents are enriched on the electricity supply side, the selection right of the users is increased, and electricity supply parties are stimulated to improve electricity service quality; meanwhile, the mode that the user autonomously selects to participate in demand response to obtain power utilization compensation is adopted, so that the ordered power utilization of the user is encouraged and guided, and the user is helped to develop energy-saving consciousness. The demand response implementation level will become the core competitiveness of each subject. Therefore, establishment of a demand response participation agent, a form and a mechanism, a specific implementation method, and the like become problems to be solved urgently.
The mechanism of demand response package at home and abroad is mainly developed from the following aspects: from the perspective of market mechanism, the electricity price making mechanism is researched; from the perspective of energy conservation and emission reduction, the emission of carbon dioxide is taken into consideration, and the utilization of renewable energy sources is improved; from the perspective of peak clipping and valley filling, intelligent air conditioner response, electric vehicle charging station pricing and the like are considered. The domestic electric power package of the residential users only considers the relation between the electric quantity and the electricity price and does not relate to demand response.
The demand response resources are various, widely distributed and difficult to control in a centralized manner, and cannot be uniformly and directly allocated by a power grid. The electric power selling company, etc. as an intermediary to cooperate with load sharing management is a currently recognized mode at home and abroad. However, electricity-selling companies are limited by the immature market environment, and only earn the difference by buying and selling electricity, and many electricity-selling companies gradually close and return to the market, and most of the electricity-selling companies are in a loss state for a long time. Therefore, the practical difficulty of solving the mechanism of the demand response development of the power selling company, namely designing the demand response package, helping the power selling company to effectively interact with the power grid and solving the deficiency of hardware equipment, is the necessary step for realizing the demand response.
The demand response is a two-way selection process requiring inquiring of the opinion of the demand side, and under the mode that the existing power selling companies are in one-to-one contact with users, the users are difficult to effectively evaluate multiple power selling companies and autonomously select a demand response mode, the users are difficult to participate in the demand response in real time at high frequency, and the market of the demand response is insufficient. Therefore, designing a reasonable mechanism to enable the demand side to effectively interact with the power selling company is a problem to be solved.
In conclusion, a reasonable mechanism is designed to enable the electricity selling company to form good interaction with the power grid company and demand side resources, provide a scene for implementing demand response, disclose a transparent competitive environment for the electricity selling company, promote market of the demand response, and meanwhile solve the problems of making a demand response package mechanism and assisting in implementing hardware equipment to guarantee user participation, so that the demand response can be remarkably implemented, and more electricity selling main bodies can be accommodated according to the electricity change trend. Overseas large energy suppliers EnergyHub participate in demand response projects by aggregating many different manufacturers and service suppliers, the business model of which may be referenced; the electricity purchasing and selling platform developed at present in China comprises a Henghua cloud electricity selling platform and a QTouch electricity selling cloud platform, wherein the Henghua cloud electricity selling platform only relates to the electronic commercialization of basic electricity purchasing and selling services without considering auxiliary services such as demand response and the like, and the QTouch electricity selling platform does not fully consider the application of the demand response in the platform.

An electric power company issues a power load adjustment requirement of a power grid on a platform in advance according to the actual production requirement of an electric power system; each power selling company divides the load adjustment task of the claiming part and the reward of the prepayment corresponding to the task amount of the power company according to own resources and technical means, decomposes the task into a plurality of demand response packages and sells the packages on a platform; and the power consumer purchases a response package on the platform, completes the response content with the assistance of the power selling company, and obtains the reward corresponding to the response package from the platform.
The demand response commercialization platform mainly solves the problem that the current demand response is difficult to fall to the ground actually: the demand response task decomposition and implementation architecture which is refined from top to bottom and step by step is provided, the original single-layer structure of 'power grid power selling-user power purchasing/power utilization' is changed, the capability of a power selling company in the aspect of promoting the bottom layer power users to participate in power grid demand response is excavated, the service range of the power selling company is expanded, the innovation consciousness of the power selling company is stimulated, and finally, the majority of power users actively and deeply respond to the power grid operation demand and ensure the safe and stable operation of the power grid. Meanwhile, under the complete marketization operation condition of the platform, three parties of a power company, a power selling company and a power user can benefit, and energy utilization efficiency improvement, resource optimization configuration, energy conservation and emission reduction are really realized.
A method for constructing an electric energy real-time transaction platform based on electric power demand response is disclosed, wherein the transaction platform comprises a demand response transaction server, a supervision center server, a database, and an electric power company terminal, an electric power selling company terminal and an electric power user terminal which are respectively interacted with the demand response transaction server; as shown in fig. 2.
(1) Electric power company terminal
And calculating the required load side power adjustment amount by the power company according to the load prediction result, the power grid dispatching regulation and the self-adjusting capacity. The load adjustment requirements will be submitted from the utility company side to the platform server in a prescribed textual format, including the adjustment location (substation/district), adjustment time period, adjustment amount, and corresponding consideration. And the demand response transaction server checks the load side adjustment demand submitted by the power company in real time and distributes the load side adjustment demand to the power selling company end.
(2) Electricity selling company terminal
The electricity selling company entering the platform divides the task from the load side power regulation requirement issued by the platform on the electricity selling entrance end according to the self resource, technical level and operation experience, and submits the division application to the demand response transaction server in a specified text format, and the demand response transaction server checks the division application in real time, calculates the reward corresponding to the task and prepays the reward to the electricity selling company.
After the load side of the power selling company adjusts the tasks at the wholesale stage, the power selling company decomposes the tasks into more specific demand response packages (including rewards corresponding to each package) according to the client type and range of the power selling company and distributes the packages to the power user side. It should be noted that the electricity generated in the package is charged by the electric power company, and the electric power selling company is only responsible for rewarding the demand response behavior of the user.
The demand response can be used for participating in power grid frequency modulation and peak modulation, the time scale of frequency modulation is considered to be minute level, and the time scale of peak modulation is hour level and above. In addition, since the willingness, ability, and manner of participating in demand response are different due to the nature and characteristics of business, residential, and industrial loads, packages for their demand responses are also designed differently. Specifically, the power package can be classified into the following three categories according to different demand response targets, aiming at commercial and residential loads:
① Peak shaving package in day cycle, the electricity selling company releases the related electric appliance electricity package of a certain date on the platform one or several days in advance for the user to choose in advance, the package information mainly comprises that each electric appliance (such as an air conditioner, a water heater and the like) is in an on/off state from several times to several times, package reward (comprising various forms of cash back, shopping tickets, points and the like), default credit value reduction and the like.
② 15 minute FM cycle, package main information includes the time period participating in FM, package reward and other additional provisions set for protecting electrical equipment, once the user selects the electrical equipment and time period participating in FM, the user authorizes the power selling company to directly control the relevant electrical equipment through relevant technical means in the time period (such as changing the temperature set value or working mode of the air conditioner, or starting and stopping the water heater, etc.), and the control lasts for 15 minutes.
③ emergency frequency modulation 'second killing', when the power grid suddenly encounters large power unbalance impact, the system frequency will fluctuate greatly, and the demand response is needed to participate in frequency modulation in time.
The industrial load such as electrolytic aluminum, ore furnace, etc. has the characteristics of uninterrupted operation, large power and stability. The industrial load demand response has huge potential, and can adjust power in a larger range in a short time, so that only the second and third packages of similar commercial and residential loads are formulated, and the industrial load demand response is used for participating in power grid frequency adjustment on the premise of not influencing the product quality and the equipment life.
(3) Electric power user terminal
Each power user can register on the user access end of the platform, browse various demand response commodities issued by each power selling company and "buy" the corresponding commodities according to self conditions and wishes, wherein the "buying" behavior of the user legally allows ① power selling companies to "prompt" the power selling companies to fulfill the purchased demand response tasks (optional, first package) according to the appropriateness if the conditions are met, ② power selling companies to conditionally take over (second package within a specified time period) the control rights of certain appliances, ③ power selling companies to unconditionally take over (third package) the control rights of certain appliances, and the power users acquire corresponding rewards from the platform after fulfilling the purchased demand response tasks according to the appropriateness.
The real-time transaction service platform has the following functions.
(1) Real-time transactions
The electric energy real-time transaction service platform has different functions when facing to an electric power company, an electricity selling company and an electric power user.
a. For power companies, the platform is a terminal that issues power load adjustment requirements.
After the load demand response becomes an implementable power grid operation adjusting means, the power company can fully coordinate and optimize the load adjusting means and the conventional power supply adjusting means when making a dispatching plan. For example, the adjustment task of a conventional thermal power generating unit with a high climbing cost can be replaced by relatively inexpensive load adjustment. After detailed calculation and evaluation, the dispatching department of the electric power company issues the load adjustment requirement and the corresponding reward measure, and the load adjustment requirement and the corresponding reward measure are provided for the power selling company managing the requirement response. The electric power company can check the registration and performance information of the related power selling companies in the platform; signing and inquiring a load adjustment contract between the electric power selling company and the electric power selling company; monitoring whether the power selling company performs the contract according to the regulations; and settling the related fee for the responding power selling company, and the like.
b. Facing to the power selling company, the platform is a terminal for selling and managing load adjustment requirements.
Different power selling companies can compete on the platform to obtain favor of power consumers. Generally, the more scientific and reasonable the demand response package made by the power selling company, the higher the technical means for assisting the user in completing the demand response, the more lossless the comfort level of the user and the higher the profit, the larger the number of the users and the higher the viscosity, thereby providing a high-quality load regulation service for the operation of the power grid. Of course, such a superior electricity selling company will "sell" more load adjustment tasks from the platform, sharing more rewards. The electricity selling company can check the public information of the power consumer in the platform; signing and inquiring a contract with a power consumer; monitoring whether the user fulfills the contract; settlement fees, etc.
c. The platform is a terminal for purchasing and participating in demand response for power consumers.
And the power consumer purchases a package suitable for the power consumer according to the demand response package issued by the power selling company on the platform and carries out demand response. The power consumer uploads the relevant information of the electric appliance on the platform, signs and inquires about a contract between the power consumer and an electric power selling company; inquiring the power utilization condition of the user; settling the electricity charge of the user and the like.
(2) Directed services
First, as an important part of the power informatization, the platform plays roles of not only a transaction place and a third party but also responsibility and obligation of a service provider and a guide. The intelligent power supply management system masters the core technology and mass data, carries out a power grid company, starts an electricity selling company, radiates each common power user, serves residential and civil power management, guides strategic transformation of the electricity selling company, assists the power grid company in macroscopic regulation and control, and improves the overall benefits of national economy.
Secondly, in order to facilitate the electricity consumption of residents, the platform is dedicated to providing all-around matching services related to the use of electric energy, and particularly for resident users without fixed cooperative objects, such as household electricity consumption energy saving, intelligent transformation and the like, users can make online consultation, appointment and home service and the like on the platform.
Then, in order to improve the competitiveness of the electricity selling company, the electricity selling company is guided to convert from the existing earning price difference mode of the air-buying and air-selling to the demand response guide, and the platform provides business consultation and technical guidance paid services for the electricity selling company, and mainly comprises massive public user data, package pricing, user response characteristics and the like.
Finally, in order to provide richer factual basis for macroscopic regulation and control of an electric power company, the platform provides information such as user electricity utilization data and demand response characteristics (response speed, response depth, response strength and the like) to the power grid, and provides data support for power supply planning, power grid planning and the like of the power system.
The database comprises an Internet of things database and an electricity utilization information database, and the database is the core foundation of the operation and service of the demand response commercialization platform.
The Internet of things database comprises data such as power utilization equipment of power users, software and hardware data of power selling companies, historical demand response conditions of the power users and database applications such as collection, management, analysis and calculation based on the data.
The electricity consumption information database comprises electric appliance demand related information uploaded by an electric power user, electric appliance use conditions (use time, use duration and the like) measured by the intelligent real-time measurement and control device, basic information of a system site, electric quantity conditions, real-time loads and the like.
