Using Matlab:

The simple power system with five busses and six transmission lines shown in Figure P1. The base apparent power of this power system is 100 MVA, The line data for the power system is given in Table 1 and the load and generation data in table 2. Taking Bus1 as Slack Bus obtain the load flow solution using: 1. Gauss-Seidel method 2. Newton-Raphson method Construct a power flow diagram and show the direction of the line flows.
