As an important technology and basic equipment for building a new type of power system, new energy storage is an important support for achieving the goal of carbon peak and carbon neutrality, and also an important field to promote the birth of new domestic energy formats and seize the new heights of international strategy. With the rapid increase in the installed proportion of new and renewable energy, it is imperative to promote the high-quality and large-scale development of new energy storage.
In recent years, Shandong's energy industry has anchored the strategic goal of "double carbon" and insisted on taking new energy storage as an important means to improve the regulation capacity of the power system. With high starting point planning, high standard organization and efficient promotion, new energy storage has flourished and has taken the lead in the country. By the end of 2022, the province has 58 new energy storage projects in operation with a scale of 1.55 million kilowatts, ranking first in the country. During the Spring Festival, the maximum charging power was 897000 kilowatts, and it participated in peak shaving for 6 times, reducing the total amount of wind and photovoltaic waste by 16.5 million kilowatt-hours, an increase of 83.5% year on year.
Firmly carry new energy storage
In November 2020, the Mount Taishan Science and Technology Forum and Energy Storage and Smart Energy Seminar was successfully held in Jinan, where well-known domestic energy storage experts and representatives of leading enterprises in the industry gathered together to examine the pulse, offer advice, exchange experience and seek common plans, marking the comprehensive deployment of energy storage applications in Shandong, which not only has practical significance, but also has long-term strategic value for Shandong energy industry and the entire energy industry. This is the internal demand to ensure the safe and stable operation of the power grid. Energy security is a global and strategic issue related to the economic and social development of the country, and it is "the largest of the country". As a major province of energy production and consumption, ensuring the safe and stable supply of energy is of great significance to promoting the economic and social development of the province. Entering the "Fourteenth Five-Year Plan", Shandong has fully and accurately implemented the new energy security strategy, firmly shouldered the mission and responsibility of green and low-carbon development, and steadily promoted the adjustment and optimization of energy structure. With the rapid increase in the proportion of wind power and photovoltaic power generation, the safe and stable operation of the power grid also brings new issues. To this end, Shandong's energy industry is bold in taking the lead and pushing forward new energy storage to speed up the problem solving and inject surging power into the all-round construction of new power systems.
This is the technical support to improve the level of renewable energy consumption. In order to solve the problem of wind and light abandonment, Shandong has deeply explored the construction of large-scale new energy storage facilities and integrated projects of scenic (fire) energy storage, and focused on promoting the pilot demonstration of energy storage, giving play to the advantages of good matching between new energy storage and new energy development and consumption, fundamentally breaking through the time and space constraints of traditional power production and consumption, realizing the space-time transfer and transformation of energy, and vigorously developing new and renewable energy, Provide solid guarantee for comprehensively improving the level of renewable energy utilization.
Fully build new energy storage
High-quality development of "four beams and eight columns"
Shandong adheres to the principle of high point positioning, overall planning, and first setting up and then breaking down, and sets up "four beams and eight pillars" from the top design of the overall structure, target tasks, development path and other systems to ensure that the high-quality development of new energy storage is "standing" and "stable".
Strengthen top-level design and build and develop "four beams and eight pillars" scientifically. Issue the implementation opinions of energy storage demonstration application, and plan the overall idea, main objectives and key tasks of the development of new energy storage. Formulate the action plan for the development of new energy storage and several measures for healthy development, and refine the annual task arrangement and specific work measures. Adhering to the principle of "refining objectives to projects, implementing actions to projects, and reflecting results in projects", we have successively selected two batches of demonstration projects with a total of 37 and a scale of 3.72 million kilowatts, explored the development path from point to area, and initially constructed the overall layout of "implementation opinions+action plans+several measures+demonstration projects".
Strengthen the concept of system and promote the construction of new energy storage as a whole. Adhere to energy storage beyond energy storage, and energy storage beyond energy storage, closely combine the construction of new energy storage with the development of clean energy, and formulate guidelines for grid connection guarantee of wind power and photovoltaic power generation projects. The above opinions are clear, adhere to the principle of "energy storage priority", take the proportion of energy storage allocation as the primary condition for the grid connection of centralized wind power and photovoltaic power generation projects, and ensure the grid connection in order according to the proportion. In 2022, there will be 54 selected projects with a total capacity of 6.93 million kilowatts, and a total of 2.7 million kilowatts of energy storage facilities will be configured, with a configuration ratio of nearly 40%, of which the lowest is 38%, and the highest is 42%, which has strongly promoted the development of energy storage.
Strengthen market orientation and take multiple measures to reduce operating costs. We will give full play to market mechanisms such as electricity trading, capacity compensation and capacity leasing to effectively channel the operating costs of new energy storage power stations. In terms of electricity trading, independent energy storage power stations are supported to participate in spot electricity trading, and the volume is not quoted in the trading time, and they are given priority to clearing as the price acceptor. In terms of capacity compensation, certain capacity compensation will be given to the new energy storage power stations participating in the spot trading of electricity. In terms of capacity leasing, relying on the Shandong Electric Power Trading Center, we will uniformly organize the leasing and use of new energy projects across the province, and the leased capacity will be regarded as the allocated capacity. By taking the above measures, about 30%, 15% and 55% of the operating costs were dredged, and the normal operation of the new energy storage power station was basically guaranteed.
The combination of blow-off shall be strengthened to ensure efficient operation. Optimize the dispatching operation mechanism and promote the innovative application of new energy storage. In the period of loose power supply, implement self-dispatch according to the market-oriented operation mode; In special periods such as tight power supply and difficulties in new energy consumption, the unified dispatching management shall be implemented according to the principle of "dispatch as soon as possible" to ensure that the new energy storage project can be connected to the grid immediately after completion, and the grid connection can be effective. From January to December 2022, the new energy storage facilities in operation will basically be charged and discharged on a daily basis, reducing the waste power by 360 million kilowatt-hours. In particular, the full discharge will be realized during the peak season and the cumulative discharge will be 50 million kilowatt-hours, providing a strong guarantee for the reliable and stable supply of electricity.
Strengthen process control and comprehensively improve safety management level. Implement full-cycle control and strengthen the safety management of new energy storage. In the project construction stage, guide enterprises to strengthen safety investment and actively adopt safety prevention technologies such as fire particle detection and advanced fire warning. At the grid connection stage of the project, the focus will be on key equipment such as storage units to carry out network-related security detection. During the operation stage of the project, online monitoring shall be implemented and the safety inspection of the whole station shall be carried out regularly; Establish a standardized implementation model for fire emergency response, especially organize emergency drills for battery compartment fire response in combination with the accident characteristics of electrochemical energy storage power stations.
