A large PV system is connected to a $13\mathrm{.}2$ kV distribution feeder with a feedpoint impedance X$/$R ratio of $3$ at the point of connection. There are four fully clear sunny days in a row. Over these four days, the inverter controller is set to operate in the following ways at full sun conditions:

Day $1$: $5$ MW output at Unity Power factor

Day $2$: $5$ MW output and producing $1$ MVAR reactive power

Day $3$: $5$ MW output and consuming $1$ MVAR of reactive power

Day $4$: $3$ MW output and producing $2$ MVAR of reactive power

If all other factors on the power system are the same each day, and if the power system voltage regulation equipment response is not factored in$,$ then which day had the highest voltage on the line at point of connection? $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ Which day has the lowest voltage on the line at point of connection?$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$
