Embodiment 1
[0055] This embodiment discloses a reactive power optimization method based on the weak point of the power grid, including:
[0056] Step 1: Define the weak points of the grid based on the voltage stability and local bifurcation theory of the grid;
[0057]Step 2: Define the load growth model based on the predicted load and power generation plan, and use the continuous power flow method to identify the weak points of the grid;
[0058] Step 3: Quickly analyze the voltage stability under the expected fault set based on the sensitivity method and Look-Ahead;
[0059] Step 4: Design preventive and enhanced control measures based on linear control theory.
[0060] Regarding step 1, it should be noted that the determination of weak nodes is an important part of voltage stability research. These nodes generally have the following characteristics:
[0061] Has the highest voltage breakdown point on the V-Q curve;
[0062] Minimum reactive power margin;
[0063] Most reactive powe...
