In the power network shown below node 1 is the slack bus

Question

Load Flow Calculation -

In the power network shown below, node 1 is the slack bus, where the nodal voltage is defined as (1.0∠0^o) pu, nodes 2, 4 and 5 are load buses, and node 3 is a generator bus where the voltage magnitude is controlled at 0,98 pu and the injected power is 0.4 pu, as shown.

Calculate the network bus voltage, network current, line losses and line power& reactive power flows.
