Embodiment Construction

[0030] A unified time-scale voltage control method with a three-state energy unit proposed by the present invention is described in detail in conjunction with the accompanying drawings as follows:

[0031] figure 1 is a structural schematic diagram of the adaptive deep-width deterministic policy gradient method of the method of the present invention. The adaptive deep-width deterministic policy gradient method includes three parts: deep deterministic policy gradient, adaptive method and deep-width neural network. Among them, the deep deterministic policy gradient part is mainly composed of evaluation network and executor network. On the basis of the actuator network and the evaluation network, the evaluation network and the target network are added to form four network structures: the actuator evaluation network, the evaluation evaluation network, the actuator target network and the evaluation target network. The method uses a deep-width neural network to fit the actuator eva...

Abstract

The invention provides a unified time-scale voltage control method with a tri-state energy unit, which can solve the current multi-time-scale voltage control method of "three-level voltage control + second-level voltage control + first-level voltage control" in the power system Problems that are difficult to coordinate and control. The present invention proposes a real-time voltage optimization and control framework that converts the three levels of voltage control into a unified time scale, uses the self-adaptive deep-width deterministic strategy gradient method to learn and optimize the system, and obtains the voltage of the tri-state energy unit in the power system Control Strategy. The adaptive deep-width deterministic policy gradient method includes three parts: deep deterministic policy gradient, adaptive approach and deep-width neural network. The invention can replace the voltage optimization and control method in multi-time scale form.

Description

technical field [0001] The invention belongs to the field of power system operation optimization and control, relates to a voltage optimization and control method that replaces traditional multi-time scale forms, and is suitable for operation optimization and control of power systems. Background technique [0002] With the application of renewable energy and distributed generation to the smart grid, according to the "EU-funded Smart Grid Comprehensive Research Program", the power system is decomposed into several cellular systems in the cellular network system of the future smart grid. In addition, many cells in the cellular network system can be regarded as tri-state energy units. Each tri-state energy unit has three states: emitting reactive power state, absorbing reactive power state and shutdown state. Traditional voltage optimization and control methods are difficult to adapt to future smart grids that require real-time optimization and adjustment of voltage. [0003]...
