In this paper, a model-based Direct Power Controller (DPC) is proposed for Hybrid HVDC. This Hybrid comprises a Voltage Source converter (VSC) using in the sending side and Line-commutated Converter (LCC) using in the receiving side. This application is potentially attractive for power flow in one direction, for example the integration of offshore wind farms. DPC controller is able to control directly...
This paper presents a novel integrated control scheme for three-level neutral point clamped (NPC) based PWM rectifier-inverter. Two measures are taken to minimize the size of dc-bus capacitors which are expensive, bulky and have a lifetime limit. Firstly, the direct power control (DPC) for front-end three-level PWM rectifier is applied, which will provide better dynamic performance for the dc-link...
A flywheel energy storage system (FESS) is associated to wind turbine (WT) to increase its penetration rate into the grid and to improve its contribution to the ancillary services. In this paper, the authors investigated a FESS associated to PMSM-wind turbine connected to the grid via a three-phase PWM inverter. The FESS is controlled by a FOC (flux oriented control) strategy cascaded with an external...
In this paper, the model-based direct power controller (DPC) is proposed for a multi-terminal high voltage direct current (HVDC) using Voltage source converter (VSC), which is able to control directly the instantaneous power and reactive power. Moreover, this DPC is able to handle the unbalanced network condition, that is unequal AC voltage due to unbalanced power supplies, unbalanced loads and unavoidable...
