Abstract

The invention provides a transient stability energy function analytical method for a power system including new energy. The method comprises the steps that a mathematic model of the power system including the new energy is built; the energy function of the power system is constructed according to the mathematic model, and approximation analysis is carried out on path continuous items in the energy function through trapezoidal integral paths; critical energy is solved through an iterative potential energy boundary surface method. According to the energy function method, the transient stability of the power system including the new energy can be evaluated fast and quantificationally.

Description

technical field [0001] The invention relates to the technical field of electric power system stability and control, in particular to an analysis method for a power system transient stability energy function containing new energy. Background technique [0002] After large-scale multi-type new energy access, whether the power system can maintain safe and stable operation is very important, and transient stability is an important aspect. Due to the uncertainty of new energy power, the possible operating scenarios of the power system have increased significantly, which has seriously increased the burden of security and stability scanning. Therefore, there is an urgent need for a rapid security and stability assessment method. In addition, the access of multiple types of new energy has brought new controllable resources to the security and stability control of the power system. How to quantitatively obtain the control amount of new energy power generation according to the stabil...
