Ricardo is supporting a test by the British Power Grid Company, which uses smart grid technology to unlock the spare capacity of electric vehicles and maximize the use of electricity from existing infrastructure while avoiding expensive network consolidation or substation replacement. The project, called AcTIve Response, will pilot a responsive, automated grid that can be reconfigured to move idle capacity to where it is needed. It will use power electronics and automatic switches to transfer power from reloaded substations to nearby substations. In November 2017, Ofgem approved a joint tender submitted by the UK Power Grid and SP Energy Network as part of the annual Network Innovation Competition. Ricardo supported the project from the initial development of concepts and recommendations and will continue to play a key role in the four-year life cycle. It is expected that by 2020, as many as 1.9 million electric vehicles will be used in London, the eastern and southeastern parts of the UK, and the UK’s electricity network will provide electricity to electric vehicles, including London’s buses and taxis, in these places. Will greatly increase the peak of power demand. Under the current regulatory system, the cost of increased capacity will be borne by customers, so the UK grid is using innovative technology to optimize existing infrastructure to reduce costs. With the AcTIve Response project, the power network is the first to actively move idle capacity around the system to support areas that use more power. This means that at night and on weekends, when people are charging their cars, they can provide extra power to the residential area, and then transfer the idle power to where it is needed during the day, such as a city center, a commercial center, or an electric car charging point. . When customers need more power, upgrading a substation, or adding a new substation and cable, it takes time, money, and can lead to disruption of road engineering. And AcTIve Response allows power companies across the UK to use these power sharing technologies to connect new customers, as well as those who demand more power, faster, and lower cost. The project is expected to save consumers 271 million pounds ($364 million) by 2030 and reduce carbon emissions by 448,000 tons. The UK power grid supplies electricity to more than 8 million homes and businesses. Bi Directions Thyristor (Triac) Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.

Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
