“…It should be noted that in both cases the supercapacitor is responding to the fast changes, while the other power balancing devices respond to the changes in a smoother way. 20 Fig. 12 shows the voltage response of the supercapacitor, the fuel cell and the electrolyzer for the period between 20:00 and 21:00.…”

“…In both cases the voltage remained between the operating region, that is, between 600 V to 740 V at the supercapacitor, between 147 V to 220.5 V at the fuel cell, and between 30 and 40 V at the electrolyzer. 20 Due to the control scheme, the supercapacitor delivers the power needed to supply the power peaks and for this reason it shows a fast-changing current. The current responses of the fuel cell and the electrolyzer show slower-changing currents, as expected.…”

Small-scale autonomous renewable energy systems have gained attention during the last years due to growing concerns in relation to an increasing world energy demand and to constraints in CO 2 emissions. Polymer Electrolyte Membrane Fuel Cells (PEMFC), wind turbines and solar panels are promising zero-emission devices to be incorporated into these systems. In order to integrate them, appropriate control designs are necessary, among other aspects. This paper presents a configuration that allows a proper operation of the fuel cell while the system is able to handle the power fluctuations produced by the wind turbine and the load. An electrolyzer is used to take advantage of the power surplus. The system is designed to supply 10 households, but can be easily extended. The objective of this study is to evaluate the technical feasibility of implementing such a power balancing set-up in DENLab, a renewable energy laboratory at

Abstract. Small distributed energy sources could be aggregated to form a virtual power plant (VPP) in order to overall improve technical and market issues. VPPs should be composed of several distributed batteries (DB) to solve the problem of intermittency due to wind and solar. This paper presents an approach to balance state of charge batteries. It is therefore to improve the lifetime of batteries in VPPs. According to the proposed method, the real-time SOC of DB will be tracking on the balancing SOC determined in VPP. During operation, the difference of SOC among DBs will be shrunk and finally the share of exchange power among DB is equal. Moreover, the duration time to achieve the balancing SOC can be determined by adjusting the exponent parameter of SOC in the presented function.

Abstract-The utilization of wind and sun as renewable sources causes uncontrollable fluctuations in power generation. Furthermore, the ratio between peak power and average power is high for systems with a limited number of households. In small autonomous renewable energy systems (ARES), energy storage is needed; however, the use of Lead-acid batteries as energy buffers is problematic, since it is not possible to cover fast power fluctuations without dramatically reducing the batteries' lifetime. In this paper Super Capacitors are applied to relieve fast changes in the battery storage system. Batteries are used to meet the energy requirements and Super Capacitors are used to meet the instantaneous power demand. At the end of this paper, a sizing method is proposed for the Super Capacitor system.
