Abstract
This paper presents a mixed-sensitivity-based robust H∞ loop-shaping partial feedback linearized control scheme to enhance the transient stability of a battery energy storage-associated standalone solar photovoltaic system. The proposed control scheme has been provided independent operating points for a generalized nonlinear dynamical model of DC microgrids connected standalone hybrid solar photovoltaic and battery energy storage system. A parametric uncertainty model is developed for the generalized dynamical model, and the noise disengaging merit of the proposed control technique has been investigated. The designed controller’s performance has been demonstrated under four different scenarios, and it is compared with the conventional PI controller for partial feedback linearized control law.
Highlights
Renewable energy sources (RESs) are substituting traditional fossil fuel to produce electrical energy due to their ecologically friendly behavior and sustainability [1].renewable energy sources (RESs) may deliver electrical power to an urban area or individual householder who are not tied with the utility grid [2]
A robust partial feedback linearized controller has been proposed in [26] for the standalone hybrid PV-battery energy storage (BES) system, and the performance is investigated under the generation change of solar PV panel
This controller offers improved performance compared with the partial feedback linearized controller, where a conventional PI regulator is applied for the linearized part of the nonlinear control scheme
Summary
Renewable energy sources (RESs) are substituting traditional fossil fuel to produce electrical energy due to their ecologically friendly behavior and sustainability [1]. An adaptive droop-based centralized controller is presented in [15] to control the energy storage system, but there are no other elements like a battery Such types of a controller cannot provide the desired voltage regulation when the demand power is varied. A robust partial feedback linearized controller has been proposed in [26] for the standalone hybrid PV-BES system, and the performance is investigated under the generation change of solar PV panel. This controller offers improved performance compared with the partial feedback linearized controller, where a conventional PI regulator is applied for the linearized part of the nonlinear control scheme.
