The research aims to determine the economic feasibility and efficiency of the system. The outcomes reveal that the system achieves a net present cost of $109,856 and an energy cost of $0.059 per unit. The cost of energy is notably lower compared to previously reported values due to careful selection of PV size, type, and location.
The most common configurations are solar-wind, wind-hydro, and solar-hydro combinations. The selection of the configuration depends on the availability and variability of the renewable energy sources, the power demand, and the geographical location of the system. 3.4. HRES without storage units
Compressed Air Energy Storage (CAES): is an energy storage system that stores compressed air in underground caverns. When energy demand is high, the compressed air is released to power turbines and generate electricity . 5. Flywheels: are energy storage devices that store kinetic energy.
The use of solar thermal energy improves the intake air temperature of the turbine generator, thereby enhancing the efficiency of ST-CAES. In consequence, ST-CAES can provide benefits to the smart grid and integrated RES.
This is greatly constrained by structure of compressor and multi-stage heat exchanger effectiveness. The use of solar thermal energy can eliminate the high-temperature limit of the compressor and complex heat regeneration subsystem, which can greatly simplify the structure of A-CAES .
The results demonstrate that electricity storage efficiency, round-trip efficiency, and exergy efficiency can reach 70.2%, 61%, and 50%, respectively. Therefore, the proposed system has promising prospects in cities with abundant solar resources owing to its high efficiency and the ability to jointly supply multiple energy needs. 1. Introduction
