On July 1, the Huadian Laicheng 101 MW/206 MWh energy storage power station demonstration project was launched in Laiwu, Jinan. After the first batch of "5+2" energy storage demonstration projects were fully completed and implemented in 2021, Shandong took advantage of the momentum. The first project of a new round of 3.1 million kilowatt pilot demonstrations launched quickly in Shanghai is marked by the opening of the new energy storage demonstration project in Shandong in 2022.
In recent years, Shandong has attached great importance to the development of new energy storage, insisted on incorporating new energy storage into the critical breakthroughs of the "14th Five-Year Plan", issued the country's first energy storage demonstration application implementation opinions, and introduced energy storage priority, level-in level-out, and priority power generation. "Policy red envelopes" include plan rewards and more pay for more work. In 2021, the first batch of "5+2" and new energy storage projects with a new energy storage capacity of 540,000 kilowatts will be built, and the new scale will be the first in the country; the country's first battery energy storage technology laboratory and the country's first commercialized compressed air energy storage project The power station was put into operation; relying on Shandong University of Science and Technology, the country's first secondary college - Energy Storage Technology College was established; Huaneng, Huadian and other central enterprises' first 100-megawatt energy storage demonstration projects have been launched... The province's new installed energy storage capacity has reached 760,000 kilowatts. An energy storage industry chain covering material production, equipment manufacturing, energy storage integration, engineering construction, consulting and testing has been built. From January to May, the province reduced about 90 million kilowatt-hours of abandoned wind and photovoltaic power, equivalent to the electricity demand of 170,000 households for one month.
Huadian Laicheng energy storage power station project, invested and constructed by Huadian International Power Co., Ltd. with a total investment of 450 million yuan, with a full designed capacity of 101 MW/206 MWh, including 100 MW/200 MWh lithium iron phosphate battery, The 1 MW/6 MWh iron-chromium flow battery has a total of 206,000 kWh per charge, which can meet the electricity demand of more than 1,000 households for a month. The project is completed and put into operation and included in the unified dispatching management of the Shandong Power Grid. It mainly participates in the province's power assistance, power grid peak regulation, energy storage capacity leasing and other services. It can consume about 100 million kWh of new energy and reduce coal consumption by about 30,000. Ton, providing strong support for the safe and stable operation of the power system and the construction of a new power system with a gradually increasing proportion of new energy.
It is reported that in terms of new technology, the project innovates the "high-voltage cascade + liquid cooling" method, adopts a 10.5 kV high-voltage cascade non-boost transformer access scheme, and solves the problem of battery parallel circulation and heat generation. The long-term energy storage technology of iron-chromium flow batteries has the advantages of low electrolyte toxicity, easy installation and expansion, improves the overall conversion efficiency of the energy storage power station, and saves more than 10 acres of floor space. In the new model, to comprehensively improve the peak regulation and frequency regulation capability, the project integrates the 9 MW/4.5 MWh energy storage and frequency regulation power station to be completed and put into operation in 2021, explores the optimization and innovation of the control system, and pioneers the "thermal power + energy storage" peak regulation and frequency regulation hybrid storage system. Energy mode, and create offline and online health evaluation systems for generators under severe peak shaving conditions of thermal power units. Regarding new value, relying on the distributed photovoltaic project on the roof of the Laicheng Power Plant under construction will promote the deep integration of photovoltaic power generation and energy storage and create a "photovoltaic-storage integration" project.
In the next step, Shandong insists on promoting the promotion and application of pilot projects, promoting deepening development through demonstration, strengthening scientific and technological research, focusing on innovation and breakthroughs, and promoting the high-quality and large-scale development of new energy storage in multi-mode, multi-channel and multi-scenario. Strive to reach a scale of more than 3.3 million kilowatts by the end of this year, and exceed 5 million kilowatts in 2025.
