Before going into deep in concept, let us first understand why we need a bus

What is generating bus?

Generator bus is also known as PV bus. In this bus active power (P i) and bus voltage (V) are known parameter. The bus voltage (V) is maintained constant by injecting reactive power into it from generating station. Reactive power (Q i) and load angle (δ) need to be calculated. All generating stations are connected with this bus. 2.

How many types of bus are there in a power system?

The subsystem represented in Figure 1(b) could be one of a small power plant working as distributed generation (DG). Most of these power systems operate only when connected to a full power system.

Load Bus, Generator Bus and Slack Bus

For load bus real power P and reactive power Q are known but magnitude and phase angle of bus voltage is unknown. Generator bus has P, V known but Q and voltage phase angle unknown. Slack bus is a virtual bus for which accounts for active power losses in various system. V and phase angle is given for slack bus.

Which bus is always connected to a generator?

This bus is always connected to a generator. Here, P Gi and |V i |are specified. Hence, the net power P i is known. The values of Q i and δ i are unknown at this bus. PV/Generator bus comprises of about 15% of all the buses in a power system. All PV buses can maintain a constant voltage as long as reactive power is within the limit.
