With the gradual rise of temperature, many parts of the country have entered the stage of meeting the peak and spending the summer. This year, the maximum unified load of Guangdong power grid reached 123.81 million kilowatts, a year-on-year increase of 1.51%; the maximum power load of Fujian power grid reached 40.63 million kilowatts, a year-on-year increase of 5.86%; the unified regulation load of Jiangxi power grid also reached 22.593 million kilowatts, a record high.

How to calculate power demand response compensation? Shandong, Zhejiang, Jiangsu and Henan have been confirmed!

The increasing peak load has great pressure on the operation of the power grid. In the past, the main means of regulating the load was orderly power consumption. Usually, the power grid company put forward the opinions on the level of orderly power consumption quota, which was decomposed into various cities after being audited by the competent government departments. Each city then managed the terminal power consumption according to the indicators of load and power consumption. However, it was lack of DSM only relying on administrative means Effective incentive and compensation, the enthusiasm of enterprises to participate is not high.

Since 2014, some regions in China have tried to introduce market mechanism into DSM, and Shanghai has become the first pilot city of demand response in China. Since then, Jiangsu, Zhejiang, Tianjin, Henan and other places have carried out power demand response work. The core goal of power demand response is that consumers can voluntarily change their electricity consumption behavior according to the price signal, and the key to achieve the goal is to establish an effective incentive mechanism.

Up to now, Shandong and Zhejiang have announced the power demand response work plan in 2020. From the perspective of incentive mode, Shandong, Jiangsu and Shanghai have tried to determine the compensation price through demand side bidding. Compared with the previous agreed compensation, the degree of marketization has been improved. The surplus of electricity purchase price difference in spot trading of renewable energy across provinces and regions has become an important source of funds for demand response.


Response capacity: form the demand side dynamic peak shaving capacity accounting for 5% of the largest direct load of the power grid in the previous year.

Market entities:

Power users and industrial users belong to the trading users of Shandong electric power market in the current year, and their electricity consumption capacity is 315 KVA or above. Among them, economic consumers (load aggregators) need to have time-sharing measurement conditions and the annual power consumption of a single household is 5 million kwh or more. In principle, the energy storage facilities on the user side and the electric vehicle charging and changing station should have the conditions of separate measurement. In principle, the response capacity of a single industrial user shall not be less than 500 kW, and that of a non industrial user shall not be less than 200 kW in principle.

In principle, if the response of a single industrial user is less than 1000 kW and that of a non industrial user is less than 400 kW, the load aggregator shall act as an agent to participate in the demand response. If the response of industrial users is more than 1000 kilowatts and non industrial users are more than 400 kilowatts, they can participate in the demand response independently or through the agent of load aggregators.

Response classification: peak shaving demand response, valley filling demand response; emergency demand response, economic demand response.

Compensation price: emergency demand response compensation includes capacity compensation, electric energy compensation and assessment cost; economic demand response compensation only includes electric energy compensation. The mode of “unilateral quotation of quantity and clearing of marginal price” is adopted, and the bid winner is determined according to the principle of “price first, time first”.

Source of compensation cost: the compensation cost of emergency peak shaving and valley filling demand response is included in the power supply cost, and the economic peak shaving and valley filling demand response compensation expense is temporarily from the capital space expenditure formed by the grid company participating in the trans provincial renewable energy spot market pilot project.


Response capacity: by 2020, the province will achieve accurate peak shaving, and the load response capacity will reach 4 million kilowatts, and the peak shaving capacity at the load side will reach about 5% of the highest power consumption load under unified regulation.

Market players: break through the participation mode of industrial users as a single subject, further gather various load types such as energy storage facilities, charging piles, commercial buildings, residential households, etc., and actively pilot the agent mode of load integrator, so as to realize efficient resource aggregation of small and scattered users. In cement, casting, ferrous metal, pharmaceutical and other industries to carry out real-time response feasibility study and pilot. This paper studies the feasibility scheme of new user demand response such as telecom operators and large data centers.

Response classification: day ahead demand response (peak cutting day demand response, valley filling day demand response), real-time demand response.

Compensation price: the demand response before the peak shaving day is subsidized according to the clearing price and effective response electricity quantity of a single response, and the clearing price is set with a price upper limit of 4 yuan / kwh; the demand response before the valley filling day is subject to the annual fixed subsidy unit price of 1.2 yuan / kwh; the real-time demand response is subject to the annual fixed subsidy unit price of 4 yuan / kWh.

Source of compensation cost: the subsidy fund for electricity demand response in 2020 comes from the surplus of electricity purchase price difference in spot transaction of surplus renewable energy power among provinces in 2019.


Response capacity target: gradually form the demand response capacity of about 5% of the average peak load.

Market entities: residential users, industrial enterprises, load integrators, users with energy storage facilities and charging pile operators.

Response classification: contract demand response and real-time demand response.

Compensation price:

For the interruptible load which is temporarily reduced by demand response (stagger peak avoidance), the price of interruptible load shall be tried out according to its response type and response speed. The price standard is 10 yuan / kW for t ≤ 60 minutes; 12 yuan / kW for 60 minutes < T ≤ 120 minutes; 15 yuan / kW for t > 120 minutes.

For the temporary increase (valley filling) load through demand response, promote renewable energy power consumption, and implement renewable energy consumption subsidy. The subsidy for renewable energy consumption in response valley period is 5 yuan / kW, and that in normal period is 8 yuan / kW.

Source of compensation fee:

In 2015, Jiangsu began to implement the policy of seasonal peak electricity price. For large industrial users of 315 KVA and above, the price was increased by 0.1 yuan per kilowatt hour on the basis of peak electricity price every morning and afternoon in July and August every day. This part of electricity fee is used to subsidize the temporary reduction of peak power load, and ensure the capital of peak price increase and the subsidy of power demand response The basic balance between exports.

The funds from peak electricity price increase are used for demand response interruptible electricity prices and renewable energy consumption subsidies. They are used in accordance with the principles of fairness, openness and transparency, and the additional funds can be used in a rolling manner over the years.


Market entities:

All industrial users with a response capacity of 500 kW or above, and non industrial users with a response capacity of 200 kW or above, whose equipment is connected to the power user’s power consumption information acquisition system and operates well, can voluntarily participate in the demand response work. The power users who meet the above conditions can directly apply for participation in demand response, or participate in demand response in the form of centralized management through power sales enterprises or power service agencies.

Response classification: contract demand response and real-time demand response.

Compensation price: agreed demand response: 60 minutes ≤ t ≤ 120 minutes, subsidy price 6 yuan / kW · time; t > 120 minutes, subsidy price is 9 yuan / kW · time.

Real time demand response: for 30 minutes ≤ t ≤ 60 minutes, the subsidy price is 12 yuan / kW · time; for 60 minutes < T ≤ 120 minutes, the subsidy price is 18 yuan / kW · time.

Source of compensation cost: the demand response subsidy cost issued by power grid enterprises is included in the transmission and distribution price.
