The increasing penetration of renewable energy sources is pushing low-voltage electrical grids to become predominantly power electronic-based. Consequently, the design and operation related grid-connected converters must be achieved under proper manner, in order maintain stability support reliable entire system. Thus, this work presents modeling control a single-phase multifunctional converter, which operates as current-controlled voltage source inverter using an LCL-type output filter. An...
This paper introduces a novel control strategy for multifunctional grid-tied inverters in industrial/commercial power systems, aiming to address the compensation of instantaneous oscillations. The proposed is derived from Conservative Power Theory, which offers ability extract and analyze oscillating terms directly <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">abc</i> frame. To demonstrate efficacy strategy, simulation results are...
AC power conditioners in electric systems have been extensively explored the literature based on approaches mainly focused single- and three-phase wiring topologies, remaining a significant gap regard to applications suitable for two-phase three-wire circuitry. Therefore, this work demonstrates that Conservative Power Theory can be employed generate proper reference signals an active filter networks. This methodology allows selectively synthesize flexible manner, providing reactive...
The primary objective of this paper is to present the basic terms Conservative Power Theory (CPT) and its applications for compensating instantaneous power oscillations in three-phase three-wire systems. reference signals a multi-functional grid-tied inverter are derived using reactive energy defined by CPT, having oscillating components directly a-b-c coordinates. compensation method proposed study validated through simulations based on practical system modeling. results presented here show...
Considering the application of multi-functional grid-tied inverters in modern microgrids, this paper proposes a novel control strategy derived from Conservative Power Theory (CPT), which makes possible compensation instantaneous power oscillations. Such approach is based on and reactive energy terms defined by CPT, allowing extraction oscillating components directly abc frame. Simulation results are presented to demonstrate applicability considering scenario weak microgrid with linear,...
In recent years, grid-connected inverters have gained wide prominence, primarily attributed to the surge in distributed energy resources. To ensure reliable operation of these inverters, it is crucial adequately damp resonance peak LCL filter at inverter output. By achieving this, guarantees system's stability while minimizing harmonic content current injected into distribution grid. address this issue, paper proposes utilization digital differentiators conjunction with optimized wideband...
The expanding use of Renewable Energy Sources (RES) has introduced a new concept microgrids, suggested in this work as heterogeneous microgrids (HMGs). HMGs comprise single-phase and three-phase RES-based distributed generators (DGs) operating together within the same microgrid to supply linear nonlinear loads. connection loads, especially ones, leads imbalances harmonic distortions currents and, consequently, asymmetric distorted voltages. This paper presents novel secondary control method...
