Electric Power System Stability and Operation
In the project given by my lecture, I have done calculate using Matlab before. I want to try Python to perform the calculation. Electrical Network Data are given below.
- Bus 1 as slack bus with V1 = 220 kV. Calculate bus voltage and power that unknown. Then calculate real power loss. Write the result on the table 2.
- Create Matrix-B then use it to calculate:
- The code on code.py
First, I need to find Voltage with Gauss Seidel Method
Vbus: [[220. +0.j] [222.59221802 -1.47934401j] [220.99923823 -2.58790192j] [217.31141086-10.41324995j] [216.4663692 -9.66877979j] [220.75227036 -3.11118912j] [219.42440185 -3.642961j]]
Find Magintude
V (Magnitude, kV)[[220. ] [222.59221802] [220.99923823] [217.31141086] [216.4663692 ] [220.75227036] [219.42440185]]
Find Angle
V (Angle, rad) [[ 0. ] [-0.00664588] [-0.01170947] [-0.04788193] [-0.04463676] [-0.01409264] [-0.01660083]]
Calculate Sbus using new Vbus
Sbus : [[ 85.9488007-68.1467101j] [ 100. +40.j ] [ 75. +25.j ] [-100. -30.j ] [ -64. -44.j ] [ -45. -15.j ] [ -50. -15.j ]]
Calculate Sloss
Sloss : [[1.9488007-107.1467101j]]
Find Ploss
Ploss : [[1.9488007]]
The Table
Bus V (mag, kV) V (Angle, rad) Pgen (MW) Qgen (MVar) PLoad (MW) QLoad (MVar) 1 220 0 85.9488007 -68.1467101 0 0 2 222.59221802 -0.00664588 100 40 0 0 3 220.99923823 -0.01170947 75 25 0 0 4 217.31141086 -0.04788193 0 0 100 30 5 216.4663692 -0.04463676 0 0 64 44 6 220.75227036 -0.01409264 0 0 45 15 7 219.42440185 -0.01660083 0 0 50 15
Ploss = 1.9488007 MW
- Calculate total load current.
