Load flow analysis
Load flow analysis is a study or numerical calculation of the power flow of power in steady-state conditions in any electrical system. It is used to determine the flow of power (real and reactive), voltage, or current in a system under any load conditions.
Nodal Matrix
The nodal matrix or simply known as admittance matrix, generally in engineering term it is called Y Matrix or Y bus, since it involve matrices so it is also referred as a n into n order matrix that represents a power system with n number of buses. It shows the buses' nodal admittance in a power system. The Y matrix is rather sparse in actual systems with thousands of buses. In the power system the transmission cables connect each bus to only a few other buses. Also the important data that one needs for have a power flow study is the Y Matrix.
Types of Buses
A bus is a type of system of communication that transfers data between the components inside a computer or between two or more computers. With multiple hardware connections, the earlier buses were parallel electrical wires but the term "bus" is now used for any type of physical arrangement which provides the same type of logical functions similar to the parallel electrical bus. Both parallel and bit connections are used by modern buses. They can be wired either electrical parallel or daisy chain topology or are connected by hubs which are switched same as in the case of Universal Serial Bus or USB.

Q9: Salalah city is planning to install a 3.0 MW wind turbine. The turbine has a 112 m rotor diameter and the
power/speed curve shown in Figure Q9. During the daytime hours (7am to 7pm) the wind speed is 12 m/s and the
cost of electricity is $100/MWh. During the nighttime hours the cost of electricity is $50/MWh and the wind speed is 6
m/s. Assume that the air density is constant at 1.2 kg/m³.
Determine the power output, wind power input, and efficiency of the turbine/generator during the daytime hours.
Determine the power output, wind power input, and efficiency of the turbine/generator during the nighttime hours
Calculate the daily revenue that the plant earns from selling electricity.
