“…The methodology proposes the idea of implementing primary BESS, secondary BESS and an SCSS. These topologies help to improve the overall the ESSs life expectancy; therefore, power allocation is divided into low, medium and high frequencies respective to primary BESS, secondary BESS and SCSS [36]. Therefore, lead-acid batteries are considered as primary BESS, and Li-ion batteries constituting a comparatively lower power rating is taken as secondary BESS; this configuration provides a pragmatic approach to HESS implementation as low life expectancy of commonly preferred lead-acid battery leads to low reliability of BESS, that can be compensated by techno-economic integration of Li-ion batteries.…”

This paper presents a comprehensive categorical review of the recent advances and past research development of the hybrid storage paradigm over the last two decades. The main intent of the study is to provide an application-focused survey where every category and sub-category herein is thoroughly and independently investigated. Implementation of energy storage systems is one of the most interestingly effective options for further progression in the field of alternative energy technology. Apart from a meticulous garnering of the energy resources regulated by the energy storage, the main concern is to optimize the characteristic integrity of the storage devices to achieve a practically techno-economic size and operation. In this paper, hybrid energy storage consisting of batteries and supercapacitors is studied. The fact that the characteristic of batteries is mostly complementary to that of supercapacitors, hybridizing these storage systems enhances their scope of application in various fields. Therefore, the objective of this paper is to present an inclusive review of these applications. Specifically, the application domain includes: (1) regulation of renewable energy sources, (2) contributions to grid regulation (voltage and frequency compensation, contribution to power system inertia), (3) energy storage enhancements (life cycle improvement, and size reduction), (4) regenerative braking in electric vehicles, (5) improvement in wireless power transfer technology. Further, this review also descriptively highlights the control strategies implemented in these domains of applications. The application-oriented review explicates the principle advantages with the hybridization of battery and supercapacitor energy storage systems that can be used as an insight for further development in the field of energy storage technology and its applications.

“…The switching law for the MOSFETs is defined by the reachability conditions: from Expression (31), it is recognized that a negative value of Ψ requires u = 1 to ensure dΨ dt > 0; similarly, from Expression (33), it is recognized that a positive value of Ψ requires u = 0 to ensure dΨ dt < 0. That switching law, summarized in Expression (35), corresponds to an inverting comparator, which is also depicted in the block diagram of Figure 2. Finally, the generation of u from u is also presented in Figure 2:…”

“…Unfortunately, the theoretical switching law given in Expression (35) imposes an infinite switching frequency [44], which is impossible to achieve using commercial MOSFETs. This implementation problem is addressed by introducing an hysteresis around the desired condition Ψ = 0 to constrain the switching frequency into a practical range [44].…”

Design and Control of a Buck–Boost Charger-Discharger for DC-Bus Regulation in Microgrids

et al. 2017

Abstract:In DC and hybrid microgrids (MG), the DC-bus regulation using Energy Storage Devices (ESD) is important for the stable operation of both the generators and loads. There are multiple commercial voltage levels for both ESD and DC-bus; therefore, the ESD voltage may be higher, equal or lower than the DC-bus voltage depending on the application. Moreover, most of the ESD converter controllers are linear-based, hence they ensure stability in a limited operation range. This paper proposes a system to regulate the DC-bus voltage of an MG accounting for any voltage relation between the ESD and the DC-bus voltage. The proposed system is formed by an ESD connected to a DC-bus through a bidirectional Buck-Boost converter, which is regulated by a Sliding-Mode Controller (SMC) to ensure the system stability in the entire operation range. The SMC drives the Buck-Boost charger-discharger to regulate the DC-bus voltage, at the desired reference value, by charging or discharging the ESD. This paper also provides detailed procedures to design the parameters of both the SMC and the charger-dischager. Finally, simulation and experimental results validate the proposed solution and illustrate its performance.
