Question

Consider a power system with three identical generators. The transmission losses are negligible. One generator (G1) has a speed governor which maintains its speed constant at the rated value while the other generators (G2 and G3) have governors with a droops of 5%. If the load of the system is increased, then in steady state.

A

Generation of G2 adn G3 is increased equally while generation of G1 is unchanged.

Q. A 10-bus power system consists of four generator buses indexed at G1, G2, G3, G4 and six load buses indexed as L1, L2, L3, L4, L5, L6. The generator-bus G1 is considered as slack bus, and the load buses L3 and L4 are voltage controlled buses. The generator at bus G2 cannot supply the required reactive power demand, and hence it is operating at its maximum reactive power limit. The number of non-linear equations required for solving the load flow problem using Newton Raphson method in polar form is
