Water towns are surging with new energy trends

Soft thicket cake, crispy sock bottom pastry, and delicious red oil river shrimp... Walking into the ancient town of Tongli in Wujiang District, Suzhou City, Jiangsu Province, the beautiful scenery of various Jiangnan delicacies wafting in the fireworks in March is unforgettable. The delicious scenery has been passed down for thousands of years in this water town, and its growth logic is also constantly evolving. The Ming and Qing dynasties, mainly composed of brick and wood structures, accounted for over 70% of the total construction area of Tongli Ancient Town. The protection of ancient buildings has directly promoted the transformation of energy use: entering the catering merchants and ordinary residential buildings here, the reporter found that the gas stove in the kitchen has already been replaced by an induction cooker. Cooking and cooking have changed from using natural gas to electricity, and the Le Hui Restaurant next to Tui Si Yuan is no longer smoking and burning every day. The person in charge of the restaurant, Zhu Liying, said that the monthly energy cost of a fully electric kitchen is only about 400 yuan, which is more than half the cost of gas saving. It is easy to control the heat when using electricity, and the taste of dishes is also guaranteed. The transformation of energy is not only in the streets and alleys, but also in the workshops and factories. Less than a kilometer west of Tongli Ancient Town, the first high-temperature superconducting low-voltage DC cable in China was connected to the factory area of Hongsheng Plastic Technology (Suzhou) Co., Ltd. at the end of last year. The cross-sectional size of this superconducting cable is less than half that of a conventional cable, but its transmission capacity is 20 times that of the latter, and the transmission conductor loss is only 1/10 of the latter. The chairman of the company, Cai Fengqin, calculated that by using superconducting direct current, the energy consumption of the production line has been reduced by at least 2%, resulting in a monthly electricity bill reduction of 30000 yuan and an annual reduction of about 500 tons of carbon dioxide emissions. Is the use of superconducting direct current as a "black technology" in factory production using a "cow knife" to kill chickens? Li Yaohong, Secretary of the Party Committee of Suzhou Power Supply Branch of State Grid Jiangsu Electric Power Co., Ltd., said that Suzhou is one of the prefecture level cities with the largest electricity consumption in China. The demand for electricity is constantly increasing, and new energy access is increasing. However, the urban space is limited, and the grid density cannot increase infinitely. Exploring the application of new energy technologies and building a new power system is an urgent task, and Tongli has been designated as a testing ground for energy applications in Suzhou. The regional energy Internet demonstration area in the north of the ancient town is the "engine" and "exhibition hall" of Tongli energy application test. The intelligent driving minibus runs on the smart road in the demonstration area. The installation of photovoltaic smart roads not only generates electricity, but also wirelessly charges small buses while they are in motion. Zhou You, the person in charge of the Technology Digitization Department of State Grid Jiangsu Electric Power Co., Ltd. Suzhou Power Supply Branch, said, "In the future, after this technology matures and promotes, it will completely solve the 'mileage anxiety' of electric vehicles." Entering this demonstration area of only 0.035 square kilometers, more than 10 innovative energy applications make people feel like they are in the future: there are photovoltaic power generation facilities on the roofs, walls, car sheds, roads, and street lights here, and low-speed wind turbines, disc solar concentrators, air heat storage equipment, steam turbines, and other equipment are gathered in the green belt... Multiple types of energy can be converted into electricity as intermediaries to meet people's needs at any time. The various first sets of energy equipment in the demonstration area are dazzling. Zhou You introduced that the core component here is a container sized micro network router. Different voltage levels of AC and DC can be converted into the required form through routers, which is like building an energy "overpass". The energy internet is not only to obtain various energy sources, but also to convert them into uniform
