This paper proposes a generalised inverse learning structure to control the LCL converter. A feedforward neural network is trained to act as an inverse model of the LCL converter then both are cascaded such that the composed system results in an identity mapping between desired response and the LCL output voltage. Using the large signal model, we analyse the transient output response of the con...
A design methodology for minimum volume of LCL filters applied to grid connected converters is proposed. It combines the determination filter parameter values (inductances and capacitances) hardware (component technology inductor construction). Using proposed strategy, different combinations L-C-L that meet standard restrictions are determined. The influence harmonic content results from consid...
In the context of microgrids, distributed energy resources (DERs) are interfaced through an LCL output filter with rest microgrid. The dynamic model this and lumped microgrid constitute set differential equations employed to design controller that allows integration DER units within modern power systems. For those control strategies based on cascade structure; shunt capacitor voltage (inner) dr...
In the published literature as well as in the most commonly used textbooks, the lateral collateral ligament (LCL) is described as having 1 attachment at the lateral epicondyle of the femur and another at the head of the fibula. In this article, we reconsider the attachments, the length of the LCL, and the tissues surrounding the LCL by presenting our anatomical observations and by reviewing the...
This paper proposes a disturbance observer-based robust model predictive control (MPC) for voltage sensorless grid-connected inverter with an inductive-capacitive-inductive (LCL) filter. A full-state estimator and grid observer are designed to reduce the number of sensors. lumped observer, considering parameter mismatch along impedance variation, is also eliminate steady-state error. cost funct...
— In this paper the class of Linearly Constrained Languages (LCL) is considered. A language L belongs to LCL iff il is the set of strings of a unambiguous context-free language L' that satisfy linear constraints on the number of occurrences of symbois. We prove that every language in LCL admits a holonomic generating function, namely a function that satisfies a linear differential équation with...
The half-bridge converter series Y-connection microgrid (HCSY-MG) is a new type of microgrid. In order to reduce the harmonic content in HCSY-MG grid-connected current and at same time simplify parameter design process LCL filter, this study proposed an filter method based on improved particle swarm optimization-least squares support vector machine (PSO-LSSVM) by analyzing characteristics curre...
