Empirical approach to regulate bus voltage range in power systems

The target voltage and maintenance range of each bus is restricted by South Korea in its grid code. As the power system becomes increasingly complex, it becomes challenging to maintain the requirements of the grid code at each hour. Under various load conditions, it is necessary to select the proper operating voltage range and fluctuation range. The analytical method of determining these quantities often makes use of optimization algorithms. However, applying optimization techniques to the power system can be a very difficult process. This paper proposes an alternative method which uses an empirical approach to determine the bus voltage range of power systems.
