Abstract

With large scale of renewable energy connected to power grid, its control for synchronous stability and static voltage support is important for the stable operation of power system. However, existing studies analyses the above two issues independently from the perspective of active power and reactive power regulation. It has not formed a set of security region analysis method and online monitoring technique comprehensively considering the line active and reactive power transmission constraint, and the renewable energy modulation constraint. This paper carries out related study. It firstly reviews the main conclusions on the renewable energy synchronous stability control and static voltage support. Then it derives the mathematical expression of renewable energy static grid-connected control boundaries, including the work point trajectory, the renewable energy modulation limit, etc. Based on this, the security region of renewable energy control is derived under different power grid conditions and different control modes, and the formulas for calculating the maximum power point, maximum current, etc. are given. The analysis conclusion would provide an important theoretical basis for the design of renewable energy stable control and online monitoring software.
