- Abstract
- This paper describes a new technique for enhancing the accuracy of high-voltage direct current (HVDC) systems in the state estimation of the Korean energy management systems. New methodology, which includes the accurate modeling of the HVDC systems using switching devices, the determination of the operating mode of the HVDC systems, and a fast-decoupled weighted least square approach with a modified gain matrix, is proposed to enhance the accuracy of state estimation. Especially, the DC current is defined as a state variable to estimate the HVDC systems. These algorithms are verified in on-line environment. The test results show that the proposed algorithm operates correctly for various situations. (C) 2013 Elsevier Ltd. All rights reserved.
