“…The SoC increases from 0 to 1 after charging for 2.5 h, and then decreases to 0 after discharging for 3.03 h. Based on (12), the global efficiency of this OCAES is estimated about 60.6%. This efficiency is reasonable although it is a little higher than those of the existing developed CAES plant in McIntosh [14]. Calculated from (13) 2.4.…”

Due to the high predictability and the high energy density, marine tidal resource has become an area of increasing interest with various academic and industrial projects around the world. In fact, several Marine Current Turbine (MCT) farm projects with multi-megawatt capacity are planned to be installed in the coming years. In this paper, a MCT farm is supposed to be the main energy supply for a stand-alone island. To compensate the MCT farm power variation relating to the tidal phenomenon, an Ocean Compressed Air Energy Storage (OCAES) system is considered to achieve the island power management. The novelty in this work is that conventional Diesel Generators (DGs) would only serve as a backup supply while the main island power supply will be fulfilled by the proposed hybrid MCT/OCAES system. A simplified OCAES model is built-up in this paper with cycle efficiency about 60.6%. Simulations under different working conditions are carried out to validate the feasibility of the hybrid power system. The obtained results show that the proposed system power management can greatly help to decrease DG fossil fuel consumption and CO 2 emission.

The Democratic Republic of Congo is facing a dramatic electricity crisis. For the population, the access to electricity is 1% in rural areas, 30% for cities and 9% nationally. Energy supply based on renewable energy source is one of the promising solutions for now or in the future to deal with the limited fossil fuel resources as well as the emission of harmful waste. Out of various renewable resources the sun, wind and biomass associated with energy storage are considered to hold one of the most promising alternative to the electricity crisis in Democratic Republic of Congo (DRC). A large central power plant associated with many smaller power sources closer to customers can provide power to all provinces, cities, municipalities and villages of the DRC holding down the price. Using renewable energy generators at the location of high harvest potential, appropriate rating and location of storage and transmission system between different regions, a cost efficient system can be achieved. This study facilitates the best storage system associated with the integration of renewable energy technology into the multiple DRC power plant systems. The benefits of such systems will include high reliability, lower cost, and fewer blackouts. This research intends to present the solution that will produce electricity from renewable energies (Sun, Wind and Biomass) into the main grid at lower cost when using a suitable energy storage system
