The load on the power plant is seldom constant rather it varies from time to time, as shown in Fig. 10.1. The load on any power plant can be conveniently considered into two parts namely: (i) Base load, and (ii) Peak load. The unvarying load, which occurs almost the whole day on the power plant is called the base load [...]
In this article we will discuss about the procedure for the formation of admittance matrix in a power system. Formation of Ybus Using Step by Step Method: The admittance matrix can be formed from the parameters of the system components. A diagonal element Yii is the sum of all admittances connected to ith bus. An off-diagonal element Yik is the [...]
In this article we will discuss about the formulation of load flow equations to determine load flow in the power system. The complex power injected by the generating source into the ith bus of a power system is given as: Si = Pi + j Qi = Vi Ii* i = 1, 2, …, n …(6.56) where Vi is the [...]
