分布式能源接入电网的协调控制问题与对策研究
分布式能源作为现代电力系统的重要组成部分，其定义涵盖了位于用户侧，可独立或并网运行的能源系统，具有高效、灵活、环保等特点，类型多样，包括太阳能、风能、储能等多种形式。在分布式能源接入电网的过程中，协调控制技术成为关键。其中，分布式电源并网技术确保了能源的有效接入，电网潮流与电压控制技术则保障了电网的稳定运行，而分布式能源调度与能量管理技术则实现了能源的高效利用。然而，分布式能源的接入也带来了一系列协调控制问题，如电压波动与闪变、频率响应能力异常、保护配置困难等。这些问题中，传统保护原理的失效和保护配合关系的复杂化尤为突出，使得控制策略的制定变得更为复杂。针对这些问题，采取有效的协调控制对策至关重要。安装电压调节设备可以减缓电压波动，提升储能系统响应速度则有助于增强系统的稳定性。同时，研发新型保护算法，加强保护配合研究并建立保护配合模型，能够提高保护系统的适应性和可靠性。此外，采用智能控制技术，如人工智能、大数据等先进技术，可以实现对分布式能源的智能调度和协调控制，进一步提升电网的稳定性和运行效率。

Abstract
As an important part of the modern power system, the definition of distributed energy covers the energy system located in the user side and can be operated independently or connected to the grid. It has the characteristics of high efficiency, flexibility, environmental protection, and various types, including solar energy, wind energy, energy storage and other forms. In the process of distributed energy access to the power grid, the coordinated control technology becomes the key. Among them, the distributed power grid-connected technology ensures the effective access of energy, the power flow and voltage control technology ensures the stable operation of the power grid, and the distributed energy dispatching and energy management technology realizes the efficient utilization of energy. However, the access of distributed energy also brings a series of coordinated control problems, such as voltage fluctuation and flicker, abnormal frequency response ability, and difficult protection configuration. Among these problems, the failure of traditional protection principle and the complexity of protection coordination are particularly prominent, which makes the formulation of control strategy more complicated. In view of these problems, it is crucial to take effective coordinated control countermeasures. The installation of voltage regulating equipment can slow down the voltage fluctuation, and improving the response speed of the energy storage system can help to enhance the stability of the system. At the same time, the development of new protection algorithm, strengthen protection cooperation research and establishment of protection cooperation model, can improve the adaptability and reliability of the protection system. In addition, the use of intelligent control technology, such as artificial intelligence, big data and other advanced technologies, can realize the intelligent scheduling and coordinated control of distributed energy, and further improve the stability and operation efficiency of the power grid.
