Synchronous Generator Active and Reactive Power Oscilations Reduction by BESS

In the presented paper, we address the threats arising from the negative transient effects in the electrical grid and we propose ways how to decrease their negative effect on the synchronous generator. The proposed solution uses BESS installed in the common electrical node with...

Design of universal H-bridge converter for cascaded multilevel topologies

A new universal multi H-bridge converter is introduced in this paper. The main purpose of proposed universal converter is simple testing of modular multilevel topologies as CHB and M2LC topology. The whole converter is designed to fit a standard 2U height 19” rack mount enclos...

Integration of battery energy storage in thermal power plant

The paper focus on the benefits of close integration of battery based energy storage directly into thermal plants. The attention is paid to use of the energy storage for primary frequency control in cooperation with classical steam turbine control. The model topology of the tu...

Optimization of reluctance motor with printed rotor

A novel way of optimizing a reluctance motor with rotor manufactured by 3D printing technology is presented. The optimization algorithms must take into account the tolerances of its production that are generally higher compared with classical processing, which requires a high level of&#...

Minimum infinity norm-based PWM for three-phase four-leg converters

Control of four-leg voltage-source converters operating on three-phase systems traditionally faces the problem of transformation from a four-degrees of freedom (DOF) modulation space to a three-DOF output-voltage space. Contemporary, it is highly desirable to minimize the leg voltage, and consequently...
