In order to solve the intermittent problem of renewable energy, many variable energy sources such as wind energy and solar energy have combined battery energy storage systems, used batteries to save excess electricity or make up for windless and sunless power vacancies, and its importance has risen year after year.
Swedish power group Vattenfall recently announced that the company's PenyCymoedd wind farm in South Wales, UK has been connected to 500 BMWi3 batteries with a total capacity of approximately 22MW, which will help stabilize the UK's power frequency and power supply and demand reliability.
According to ClausWattendrup, head of Vattenfall's solar and battery business, the company uses existing wind farms to achieve energy multiplicative, which is Vattenfall's current largest battery installation project, and these hybrid renewable energy fields will become increasingly important and maximized in the future. effect.
The PenyCymoedd228MW wind power plant in the UK was completed and put into operation in 2017. It supplies 15% and 188,000 households in Wales with an annual reduction of 300,000 metric tons of carbon. Now the plant has been successfully connected with six large integrated batteries. Use 500 BMW batteries to increase the flexibility of power dispatching for wind farms.
Gunnar Groebler, head of Vattenfall's wind energy business, pointed out that the company is gradually moving towards a smart, digital future and is expected to reach a carbon-free enterprise in this generation.
The National Grid approved the “Battery@PyC” plan proposed by Vattenfall in August 2016. Vattenfall signed an agreement with BMW in March 2017 to trade 1,000 33KWhi3 batteries and BMW battery control system. The first batteries have been used in the Netherlands. The onshore wind farm, Princess Alexia, adds 3.2 MW of energy storage to the 122 MW wind farm.
In response to world trends, major automakers are now developing their own electric vehicles or batteries, hoping to do their part for the earth and the environment, and Vattenfall is not the first example in the world to use traditional car manufacturers' batteries to stabilize the grid. .
Renault announced in April 2018 that it intends to transform the Portuguese island of Porto Santo Island into a "smart island", using smart grid sensors, smart meters, and decentralized energy management and battery energy storage systems to achieve carbon-free sustainability.
