company news about Promoting high-quality development of distribution networks

The large-scale development of new energy and new loads urgently needs to improve the carrying capacity of the distribution network. One is to enhance the carrying capacity of distributed new energy. In recent years, distributed photovoltaics have developed rapidly. As of the end of 2023, the cumulative grid connected installed capacity of distributed photovoltaics has exceeded 250 million kilowatts, accounting for 41.8% of the total installed capacity of photovoltaics. Distributed photovoltaics have the characteristics of difficult to predict development and construction scale in a timely manner, inconsistent development layout and output characteristics with load. Currently, the carrying capacity of distribution networks in some areas is approaching its limit, and the problem of reverse power transmission is prominent, posing great challenges to the safe and stable operation of the power grid. Secondly, it is necessary to enhance the carrying capacity of new loads such as electric vehicles. As of the end of 2023, the number of new energy vehicles in China exceeded 20 million, and the total amount of charging infrastructure reached 8.596 million units. The randomness of electric vehicle charging may exacerbate the peak valley difference of the load, bringing certain impacts to the safe and reliable supply of electricity. With the accelerated development of electric vehicles, it is urgent to further enhance the carrying capacity of the distribution network, providing a solid physical foundation for ensuring electricity demand and large-scale vehicle network interaction.
