Research on Hybrid Energy Storage for Stand-alone PV System
ABSTRACT: Standalone PV system with hybrid energy storage could be a promising solution for powering up off-grid or that have no access to grid electricity. The objective of the control of this hybrid energy storage standalone PV system is to maintain the stability of the DC bus voltage, at the same time to supply the desired power to the load of the PV and hybrid energy storage through coordinated control of power electronic converters. In this paper implementation for a hybrid system in a photovoltaic system with battery and supercapacitors to maintain continuity in the supply is presented. Virtual resistance droop (VRD) controller is proposed to regulate battery converter and a virtual capacitance droop (VCD) controller is implemented for supercapacitor (SC) converter. The SC is used to minimize the imbalance power in the system, due to the slow dynamics of the battery. thus Supercapacitors are used to reduce the stress and increase the life of the battery by providing or absorbing peaks powers as demanded by the load. The photovoltaic cells are connected to DC bus with boost converter and controlled with MPPT algorithm, Supercapacitor and batteries are linked to the DC bus through the buck-boost converter and the load is connected to the DC bus. The effectiveness of proposed scheme is shown by simulation studies in MATLAB/SIMULINK

A renewable energy driven microgrid system can be designed by integrating with optimally sized renewable energy source such as Solar PV with Battery Energy Storage System (BESS) and Thermal Energy Storage System (TESS). Microgrids integrate Renewable energy source with the other energy mix intelligently. They seamlessly balance the variable output of renewable energy with traditional generation assets. In doing so, the microgrid overcomes the downside of solar energy as they only generate power when the sun shines without any human intervention. In this research study the attempt is made to carry out design engineering of Hybrid Microgrid System to meet Thermal and Electrical demands of the building in optimized and cost-effective way.

Modeling the hybrid batterysuper storage system for a solar standalone microgrid
World Academy of Science, Engineering and Technology, 2023
Solar energy systems using various storages are required to be evaluated based on energy requirements and applications. Also, modeling and analysis of storage systems are necessary to increase the effectiveness of combinations of these systems. In this paper, analysis based on the MATLAB software has been analyzed to evaluate the response of the hybrid energy system considering various technologies of renewable energy and energy storage. In the present study, three different simulation scenarios are presented. Simulation output results using software for the first scenario show that the battery is effective in smoothing the overall power demand to the consumer studied during a day, but temporary loads on the grid with high frequencies, effectively cannot be canceled due to the limited response speed of battery control. Simulation outputs for the second scenario using the energy storage system show that sudden changes in demand power are paved by super saving. The majority of these sudden changes in power demand are caused by sewing consumers and receiving variable solar power (due to clouds passing through the solar array). Simulation outputs for the third scenario show the effects of the hybrid system for the same consumer and the output of the solar array, leading to the smallest amount of power demand fed into the grid, as well as demand at peak times. According to the "battery only" scenario, the displacement technique of the peak load has been significantly reduced.

Indonesian Journal of Electrical Engineering and Computer Science
This paper present on the analysis of an energy storage sizing for a small grid-connected PV system. This project is to study the proper sizing of energy storage (battery) in a grid-connected PV system for consumers whom purchase and sell electricity from and to the utility grid. The goal is to minimize the total cost of the operation for a consumer with a PV system with a battery storage system. This is to make sure that minimizing the total annual operating cost while maintaining an efficient system. This study uses typical consumer load consumption, and solar irradiance data throughout a year, while varying the type of battery storage (study lead acid and Lithium ion battery) as an energy storage for a similar system. Since lithium ion is not the main options to be integrated with PV system, this study will then reveal the data in terms of cost on why it is not a popular choice.
Study of Hybrid Energy Storage System for High Rate Power Mitigation in Microgrid
Proceedings of the 2018 2nd International Conference on Electrical Engineering and Automation (ICEEA 2018), 2018
Energy storage system (ESS) is integrated to a microgrid for managing the intermittent power from the renewable energy source. The battery energy storage system (BESS) is widely used in a microgrid, but it has various factors such as a high current of discharge/charge that affect the lifespan and quality of the BESS and lead the extravagant investment for replacing the BESS. This paper studies the using HESS consist of BESS and supercapacitor (SC). The SC well operates at the high rapid change of current of discharge/charge. The study was performed in MATLAB/Simulink program. The study results showed the HESS application to accommodate the quick change of load variation or the fluctuation of distributed generator (DG) output that help to reduce the fluctuation in the microgrid. This method can improve power and reduce the stress on BESS for dilating the lifespan.
The hybridization of renewable energy systems (RES) and further integrating them with Energy Storage Systems (ESS) can help improve the RESs' reliability and reduce the mismatch between energy consumption and generation profiles. The main aim of this study is to suggest a sizing methodology for the RES components with various ESS scenarios in a microgrid through techno-economic feasibility analysis. Although the suggested methodology is flexible to include several RESs and ESSs, the methodology is demonstrated to compare the techno-economic performance of Wind and Photovoltaic (PV) energy systems under four different ESS scenarios; (i) no ESS, (ii) Pumped Hydro Storage (PHS), (iii) Hydrogen Fuel Cell (HFC), and (iv) hybrid ESS (PHS/HFC). The optimal RES configuration is determined by maximizing the RES fraction while equating the Cost of Electricity (COE) to the national utility tariff. However, in the event that there is no feasible system configuration that satisfies the mentioned criteria, the main objective becomes maximizing the RES fraction at the lowest attainable COE. This study outlines that the incorporation of PHS and HFC with the PV/Wind hybrid system increased the demand-supply fraction from 46.5%-89.4% and the RES fraction from 62.6%-91.8% with COE equals to 0.175 USD/kWh. Even though the integration of PV and wind systems improve the performance of the system by offering better matching between the energy consumption and energy generation profiles, the PV/wind hybrid system is still unreliable, and it needs an energy source that can provide constant energy to meet the baseload or part of it depending on the control strategy (Jaber, Al-Sarkhi, Akash, & Mohsen, 2004). As a solution, the integration of Energy Storage Systems (ESSs) along with the hybridization of solar and wind systems allows the achievement of high levels of renewable energy fraction and Demand-Supply Fraction (DSF) paving the way to the development of microgrids that runs on https://doi.
