EP Capacitor Sizing Quiz

What is the main objective of the EP-based capacitor sizing code?

• Reduce active power loss

• Improve voltage profile by maximising Vmin

• Increase line current

• Reduce CPU time

What is the population size (pop) used in this simulation?

• 5

• 8

• 10

• 15

How many capacitor banks are installed in each individual solution?

• 2

• 3

• 4

• Depends on the generation

What does Qd_data = [Qd_bus Qd_value]; represent?

• Load flow results

• Location and amount of added reactive load

• Final voltage values

• Mutation factor

What is the purpose of randperm(num_PQ, tot_install_Qc)?

• Sort bus numbers

• Select best 3 capacitor values

• Randomly choose 3 bus locations for Qc installation

• Assign minimum Qc to each bus

What is the meaning of the variable Vmin?

• Maximum voltage

• Total voltage loss

• Minimum voltage across buses

• Voltage at slack bus

Why do we use round(rand_vals / interval) * interval when assigning capacitor values?

• Ensure Qc values are integer only

• Limit Qc to binary only

• Enforce step interval of 5 for capacitor values

• Remove decimal errors

What is beta used for in the code?

• Load flow results

• Random value from Gaussian distribution

• Qc max values
