Features of new power system with new energy as the main body

(4) Insufficient support capacity of electric power equipment. Facing the characteristics of the new electric power system, the adaptability of the existing power transmission and transformation equipment needs to be upgraded, and it needs to develop in the direction of more agile, more intelligent and higher carrying capacity. In particular, the overload bearing capacity of existing power electronic devices for power systems is low, which physically determines the vulnerability of equipment and systems, and it is urgent to improve the level of devices. In addition, the practical level of large-capacity energy storage systems needs to be improved, and cost, safety and efficiency are still the main obstacles to the large-scale promotion of energy storage.

(5) The basic theoretical system of the power system needs to be improved. The problem that the traditional power system technology system does not adapt to the development of large-scale new energy and power electronic equipment gradually appears. At the planning level, the concept and method of power quantity balance and capacity adequacy should be transformed from the current deterministic thinking to the probabilistic thinking. At the operational level, it is necessary to deeply grasp the dynamic characteristics of power electronics and improve the means of system analysis in complex environments.
