Energy storage system design, planning and implementation for distributed generation systems

In this study, it is planned to use the Corn Stalk-HCl-Tin catalyst, which is synthesized by treating HCl-supported Tin (Sn) with Corn Stalk to accelerate hydrogen production, as a dual-functional energy support unit, as an active supercapacitor material to store electricity at the same time. In the comparisons made as a result of electrochemical findings of the produced prototypes such as galvanostatic charge/discharge (GCD), Cyclic voltammetry (CV) and impedance spectroscopy (EIS) curves, it was found that they were largely similar to the supercapacitor curves in the literature, had a remarkable capacitive value (146.253 F/g) and it has been determined that it accelerates hydrogen production by showing a catalyst effect as in the catalysts literature. In the light of all this information, the produced prototype hybrid energy support system from this dual-functional material is used as fuel cell/battery under unpredictable clouding and meteorological conditions, when the energy demand peaks instantaneously in the grids containing distributed generation systems or when the power supply is out of production at night in systems containing PV. It is intended to be used in the design of storage systems. In order to provide the required amount of energy, a large-capacity hybrid energy storage system was designed by connecting serial and parallel in the form of prototype stacks. This designed energy source has been simulated in a microgrid with the Alkumru hydroelectric power plant and a 50 MW hydro-solar solar power plant in Siirt province, together with a hybrid energy storage system including super capacitor and fuel cells designed from new dual-function material, in a microgrid with HOMER Pro software. As a result of the analysis, the proposed hybrid combination is techno-economic due to its relatively low energy unit cost (COE), ($0.138/kWh) and net present value (NPC), ($984M) compared to the other option (0.139$/kWh, 983M$) was found to be more appropriate. The annual total energy productions for the two system designs are considered on the basis of system components. In the two power system configurations, a design has been put forward in which a part of the power demand in the system where the FC is located together with the SC is met by the FC, thus preventing possible power cuts. In addition, it has been demonstrated by the analyzes that the operation and maintenance costs of the power system containing SC increase in the absence of FC in the power configuration.
