The faults in a microgrid (MG) pose many challenges for operation of the system. They may lead to an increase in the operation cost. In this paper, in order to solve the problem, a novel algorithm based on the auto-configuration of MGs is proposed for minimizing the operation cost in grid-connected mode. A centralized energy management system (EMS) is also developed in accordance with the proposed...
Direct current (DC) connection of the large-scale wind generations with high voltage levels and long distance has been widely developed. Meanwhile, medium voltage direct current (MVDC) can also offer similar benefits compared to high voltage direct current connection of wind generations. This study presents a comparison study of MVDC and MVAC for the integration of distributed wind generations. The...
This paper presents a model predictive control for the superconducting magnetic energy storage (MPC-based SMES) system, which can be applied to a voltage source converter and a dc/dc chopper in the SMES system together. The SMES system is implemented in a microgrid to control the constant power flow at the point of common coupling, frequency, and voltage of microgrid. The control performance of the...
