1, what is the ladder price
"Ladder step-rate electricity price", commonly known as "ladder tariff," refers to changing the current price of residential electricity in the form of pricing to sub-unit pricing based on the amount of electricity consumed by users, and the increase in electricity prices with step-by-step increase in electricity consumption. Electricity pricing mechanism.
Starting from July 1, 29 provinces (autonomous regions and municipalities) except Tibet and Xinjiang will implement residents' ladder electricity prices and undergo hearings in May and June. At present, the final implementation plans have been announced.
2. The impact of policies on the use of smart meters
The implementation of ladder price also has a profound impact on the management of smart meters, such as:
1) The implementation range of residential ladder electricity price is: the implementation of "one household, one meter" urban and rural residents in the power supply area of ​​the provincial grid;
2) Resident users using prepaid energy meters: before remote automatic meter reading can be performed, the electricity price can be executed on a yearly basis for the purchased electricity;
3) The use of a meter with a remote meter reading function meter, before the realization of remote automatic meter reading, should follow the meter reading cycle of power supply companies to implement the ladder price. The meter reading period of the power supply company shall not exceed two months in principle;
4) For residents who have not implemented the “one household, one form†resident table and non-resident users (such as schools) that implement residents’ electricity prices, the residents’ ladder price will not be implemented. The level of electricity price is adjusted slightly below the weighted average price increase level of the third-grade electricity price;
5) Encourage residents to use electricity to implement peak-to-peak electricity price. Based on the implementation of the residents' ladder price, local governments can formulate the peak-to-hour electricity price ratio for residents. Whether to implement the peak-to-hour electricity price is left to the residents to choose. The resident users who choose to implement the peak-to-hour electricity price, whose peak-hour time-sharing meter is installed by the grid companies free of charge;
6) The increased revenue of the grid companies after the implementation of the ladder tariff is mainly used to make up for the increase in the desulfurization costs, the renovation of electricity meters for residents, and the increase in fuel costs for power generation companies;
7) Residents use households as a unit in principle, and a house is a household. If there is no real estate certificate, the electricity meter installed by the power supply enterprise for residential users shall be the unit.
3. The technical impact on smart meters
3.1 The Impact of the Ladder Price Policy of Each Province on Smart Meter Technology
At present, 29 provinces in the country have introduced at least two kinds of ladder electricity price execution plan: From the implementation of the ladder electricity price implementation plan announced by the provinces, the various requirements of the plan, for the implementation of the ladder electricity price settlement from the meter, the demand of different provinces will directly lead to the table The technical complexity of the meter, including the meter's clock accuracy, switching cycles, billing storage, fault memory, display, etc., adds to the technical complexity in these areas. This requires timely communication with the power company, or it will lead to A series of questions after delivery.
1) According to the monthly settlement plan, the plan will be implemented continuously throughout the year: all provinces have proposed such a settlement method;
2) According to the annual settlement plan: According to the annual total electricity, the annual total electricity will be settled within an average of 12 months, according to the ladder electricity and the phase price automatically jump; such as Zhejiang, Shanghai and other places
3) According to the monthly settlement plan and the peak-to-peak hourly battery charge increase price combination plan; such as Zhejiang;
4) Implement ladder electricity price by monthly subsection: According to the monthly settlement plan, step price settlement will be implemented in the wet and dry seasons or in different electricity months. If the tariff is executed during the wet season, and the dry season is not implemented, such as Guangdong and Yunnan , Hunan, Guizhou, Shanghai;
5) Subsidy for subsidy users - Some provinces: Each province has a subsidy offer ranging from 10 degrees to 30 degrees per month, targeting only low-income households.
3.2 The change of the phenotype of the smart meter with the ladder price function
State Grid Corporation of China now stipulates that the phenotypes with ladder function are mainly two kinds of phenotypes, local fee control and carrier local fee control. From the current policy of the ladder price, the future power company needs the step price function for remote metering. Urgently, this is mainly due to changes in the method of settlement of the ladder price, which has a direct relationship with the electricity law and price settlement.
1) Smart Remote Charge Control (RS485) - With Stepped Price (New Development)
2) Smart Remote Charge Control (Power Line Carrier) - With Stepped Price (New Development)
3) Smart Local Cost Control (CPU Card) - Existing Ladder Function, Needs Correction
4) Smart Remote Local Cost Control (Carrier CPU Card) - Existing Ladder Function, Needs Correction
5) Rural Net Watch - (RS485) - With Step Price (New Development)
In the development of these functions of the meter, it should be noted that with these ladder price settlement functions, you must consider the issue of settlement storage, you need to consider the metering fault caused by the transfer problem, you need to consider the time when switching the ladder, you need to consider a variety of The problem of switching between ladders requires peak-to-valley time ladder price increases.
3.3 Changes in the use of electricity marketing settlement management
The first scheme: The smart electricity meter is used as the main body to carry out the ladder electricity price settlement
In this scheme, the main station is only used as an electric energy collection and copying management platform, through which the remote charging price can be used to perform the pull-closing operation;
The role metering meter is used as the main electricity price settlement subject. The phenotype can be selected by the local fee-controlled smart meter; for example, the ladder electricity price, the peak-valley electricity price monthly settlement method, the annual settlement method, and the periodic settlement method are all calculated through the meter. get on. The meter will automatically accumulate and execute the ladder jump switch and settle the electricity price.
The second solution: the main station implements the real-time implementation of the ladder price execution function
In this scheme, the main station serves as the settlement entity, and formulates the management plan for the ladder price, and formulates the functions of the carry-over, execution, and statement processing of the ladder rates, and can also exchange data to the MIS marketing and billing system for processing. The main station is responsible for collecting the data of the on-site metering. The master station automatically accumulates the change value of the monthly electricity, which can be collected through the power line carrier or other dedicated channels. The data can also be recorded manually or semi-manually and then fed back to the master. Station or marketing billing system, this program emphasizes the master station's overall management capabilities.
