Used to ensure a stable supply of power system, energy storage battery south early substation ~ ~ Hokkaido grid
Introduction of electric power system the meaning of the energy storage battery
Hokkaido yong 払 anping county town, located in the Hokkaido grid south of here early to substation, starting in April 2022, using the energy storage battery power system (all vanadium flow batteries).About 150 m by 45 m in wide area, about 40 all vanadium flow batteries equipment lines, is very spectacular.Its capacity is 17000 kW x 3 hours: 51000 kWh.Is the world's biggest vanadium flow batteries all facilities.
Hokkaido region can be hooked up to the amount after reaching limits, according to the power fluctuation of wind power and solar power, electricity providers each trying to ease, there are many service providers for the energy storage battery, and the energy storage battery set is set up by electric power transmission and distribution service providers in the power system facilities.In power system, the set of large energy storage batteries, power service without the need for a separate attached energy storage battery, the battery system as a whole heap of reduced, can further reduce the cost.In addition, electricity service providers also need to alleviate the power fluctuations, the management of pressure decreases, and the electricity providers to bring many benefits.
At the end of the day, compared to other electric power company, Hokkaido system belongs to small capacity, in the process of further introduction of renewable energy, adjust the capacity limit of problems surfaced.Therefore, Hokkaido grid for renewable energy grid, adopted a phased to expand its way can be hooked up to the quantity.Can say that the introduction of the energy storage battery power system, is the effective measure to solve the issue.Responsible for power system planning, is engaged in the energy storage battery in Hokkaido's power grid of the project introduced this Mr Cool interface are introduced through:
"Hokkaido has headed by wind power renewable energy the huge potential.Therefore, in order to further introduce periodically renewable energy, the company has taken related measures.Even so, adjust ability has reached the limit, so for wind power service, we have ease power fluctuations in demand.Requiring service set up at the scene of the individual energy storage batteries, in order to realize the smooth wave.But with the increase of wind power services, the State Council also have reported in power system, the focus on energy storage batteries will be more efficient, in order to set up in the form of Shared storage battery, we raise the wind power service, decided to carry out the large energy storage battery import business."Mr (in the)
So called for in the power system of Hokkaido, with participation of wind power generation service provider, the energy storage battery power system introduced project officially started.
In new outbreaks, extremely cold, and promote the construction project in bad weather
Sumitomo electric industries since 2015, with Hokkaido electric power in the south of early substation has launched a three-year total vanadium flow batteries large-scale empirical test.Since that time, the RF technology department the first storage battery technology leader Lin Xiu department as head technology involved in the project.
"In evaluating all vanadium flow batteries at the same time, the performance of surrounding ease the impact of renewable power fluctuations on the system, and to achieve maximum efficiency and life, we are committed to the optimization of the energy storage battery power system control and the establishment of operation technology, realize the stable and safe operation.In 2019, Hokkaido electric power decided to introduce and use the energy storage battery power system, and surrounding the procurement conducted a public offering.We enter the bidding stage."(Lin)
Although conducted empirical experiments together, but this does not mean that sumitomo electric has the advantage.On the premise of "high fairness and transparency", the company for the bid.Hokkaido branch long hashimoto honest reviews the situation at that time.
"The biggest problem in all over the cost of the vanadium flow batteries.Although the price feels more difficult, but by Hokkaido electric power with the previous communication, the group in terms of technical strength won the praise and trust.So the bid, we feel gratified.At the same time, is about to start to use the tension also climbed up the heart."(hashimoto)
In July 2020, the total vanadium flow batteries equipment construction.Lin Xiu company continue as a project manager is responsible for site management.He saves time and cost in the all process.But suffered a new outbreak of crown this obstacle.In this case, the first battery technology group's three valley a abundance as the agents involved in the construction.
"Because of the outbreak of the new champions league, railway, harbor container objects cannot be reached, such as personnel have also been restricted.From the start of construction on the delay, in March 2022 plan completion period is imminent.I am involved in holding the strong field work.After the winter, the scene again face the problem of extreme cold.We began to work from early morning, the temperature as low as 25 ℃ below zero.Observations of snow, and the largest in the history of equivalent storms and typhoon bad weather also disturbing.To compensate for delay work part, we kept fighting."(3) valley
Hokkaido to enhance the potential of renewable energy
In November 2021, nearly completed construction project.From November until delivery of products, the group carried out the experiment.Test is the third battery technology, head of the group's FuYuan xiang ping.FuYuan during college in energy storage battery as the research object, induction, mainly in Morocco, outside of Japan regions such as Taiwan and Belgium to participate in the all vanadium flow batteries business.During the trial, the PCS (Power Conditioning System) related issues.
"PCS is a direct current into alternating current (ac) can be used in household appliances, etc.It is shouldering the converting electricity power system of electric power, the total vanadium flow batteries is a very important device in the system.But PCS failed, unstable.We adopted outside Japan national production of products, so you must please adjust technicians to Japan, but due to the outbreak of the new champions league, the technicians can't come to Japan.We through the remote communication way, finally solved the problem, it left a deep impression on me."(FuYuan)
In many members, led by FuYuan, under the concerted effort of, March 31, 2022, completed on schedule.Three valley think can catch the delivery date is really a big "miracle".Battery storage devices hooked up to the moment, the project manager Lin "tears"."We play in this program the comprehensive strength of sumitomo electric industries" (Lin).Since then, vanadium flow batteries all equipment delivered to Hokkaido electric grid.Mr Expressed his thanks to this mentioned above in this: "can complete the project on schedule under new crown outbreak, we felt the profound power of sumitomo electric."
The project set up by Hokkaido grid energy storage electric power system side, the relevant expenses shall be borne by wind power providers (9).Hokkaido grid first adopted the "based on the energy storage battery power system wind power to raise program (phase I)".The selected works, the 15 priority grid service, a total of 162000 kW.About this in the future business, Mr Says:
"We confirmed that the impact of the system, at the same time for periodic expand the amount of wind power to introduce, we were divided into the first stage and the second stage to collect, in the first period, as the technology feasible, we will raise capacity is set to 600000 kW.The remaining capacity is 438000 kW, is now promoting additional offering process.We hope that the future introduction of energy storage batteries, maximize the Hokkaido the potential of renewable energy."Mr (in the)
To establish the presence of vanadium flow batteries in Hokkaido, sumitomo electric challenge has already started.
In 2015, together with the Hokkaido electric power co., implementation of all vanadium flow batteries large-scale facilities used in the empirical test
