Based on problem $6\mathrm{.}50,$ please solve paragraph a and b$.$

a$)$Explores economic dispatch with fixed generator parameters.

b$)$ relationship between generator outputs, costs, and dispatch optimization.

$6\mathrm{.}50$ Use PowerWorld Simulator to determine the Mvar rating of the shunt

capacitor bank in the Example $6\_14$ case that increases V$\_(2)$ to $1\mathrm{.}0$ per unit.

Also determine the effect of this capacitor bank on line loadings and the

total real power losses $($shown immediately below bus $2$ on the oneline$).$

To vary the capacitor's nominal Mvar rating, right$-$click on the capacitor

symbol to view the Switched Shunt Dialog, and then change Nominal

Mvar field.
