“…Moreover, dissipated energy originates when wind power production is insufficient to operate the compressor, when the diesel generator operates at a higher regime than required or when the ESS is full. In this case, a dump load must be added to ensure power balance according to Equation (1).…”

A hybrid system combines two or more energy sources as an integrated unit to generate electricity. The nature of the sources associated varies between renewable and/or non-renewable energies. Such systems are becoming popular as stand-alone power systems to provide electricity, especially in off grid remote areas where diesel generators act as primary energy source. Wind–diesel systems are among the preferred solutions for new installations, as well as the upgrade of existing ones. However, efforts to address technical challenges towards energy transformation for sustainable development are multiple. The use of energy storage systems is a solution to reduce energy costs and environmental impacts. Indeed, efficient and distributed storage not only allows the electricity grid greater flexibility in the face of demand variations and greater robustness thanks to the decentralization of energy sources, it also offers a solution to increase the use of intermittent renewables in the energy mix. Among different technologies for electrical energy storage, compressed air energy storage is proven to achieve high wind energy penetration and optimal operation of diesel generators. This paper presents a computer model for performance evaluation of a wind–diesel hybrid system with compressed air energy storage. The model has been validated by comparing the results of a wind–diesel case study against those obtained using HOMER software (National Renewable Energy Laboratory, Golden, CO, United States). Different operation modes of the hybrid system are then explored. The impact of hybridization on time and frequency of operation for each power source, fuel consumption and energy dissipation has been determined. Recommendations are made on the choice of key parameters for system optimization.

“…Thus, the lack of connection to the national electric network makes those communities rely solely on local generated electricity. Most off-grid communities and industrial sites rely on diesel gensets to generate electricity [1].

“…As a result, diesel gensets are used as main source of electricity. However, the main drawbacks of this solution include: the cost to generate a kilowatt-hour of electricity versus the associated fuel procurement cost [1][2][3], the environmental impact of using fossil fuels [4] versus the system efficiency [5]. One way to tackle these issues is the use of renewable energy systems.…”

Remote and isolated communities in Canada experience gaps in access to stable energy sources and must rely on diesel generators for heat and electricity. However, the cost and environmental impact resulting from the use of fossil fuels, especially in local energy production, heating, industrial processes and transportation are compelling reasons to support the development and deployment of renewable energy hybrid systems. This paper presents a computer model for economic analysis and risk assessment of a wind-diesel hybrid system with compressed air energy storage. The proposed model is developed from the point of view of the project investor and it includes technical, financial, risk and environmental analysis. Robustness is evaluated through sensitivity analysis. The model has been validated by comparing the results of a wind-diesel case study against those obtained using HOMER (National Renewable Energy Laboratory, Golden, CO, United States) and RETScreen (Natural Resources Canada, Government of Canada, Canada) software. The impact on economic performance of adding energy storage system in a wind-diesel hybrid system has been discussed. The obtained results demonstrate the feasibility of such hybrid system as a suitable power generator in terms of high net present value and internal rate of return, low cost of energy, as well as low risk assessment. In addition, the environmental impact is positive since less fuel is used.Energies 2019, 12, 4054 2 of 23 making well suited for the deployment of hybrid systems. Wind-diesel hybrid system with compressed air energy storage (WDCAS) appears as a cost-effective alternative to supply electricity and to ensure diesel generator operational efficiency. The combination of these sources with an energy storage system (ESS) helps to balance variations in power supply and demand.A wind-diesel hybrid system is a stand-alone power system with wind and diesel generators. These systems are recommended for medium scale applications when the use of diesel generators is unavoidable. ESS integration facilitates a hybrid stand-alone system to optimize energy usage while maintaining efficient demand response. Compressed air energy storage (CAES) appears as an economically mature technology. Cost, simplicity, lifespan, fuel consumption and greenhouse gas (GHG) emissions are all influential factors that determine the competitiveness of this technology for wind-diesel hybridization. Moreover, CAES represents a promising solution to store electricity derived from kinetic energy of air at a particular time for further utilization.WDCAS operates according to compression-decompression cycles. The overall performance is subject to load power requirements, energy sources availability and energy storage level. The principle consists of two main phases. During high wind speed conditions, the excess of air is compressed and stored in a reservoir, when the energy is needed, the stored compressed air is released to drive a turbo-generator for electricity production. During low wind speed conditions,...

Abstract:In order to improve energy efficiency and protect the environment, new energy vehicles have been developing vigorously. As one kind of the vehicles, CNG (Compressed Natural Gas) Automobiles and CNG & Electric hybrid cars have been accelerating promotion. However, the current CNG vehicles are reducing the pressure of CNG through a reducing valve, so that achieves the intake gas pressure to the engines. Undoubtedly, it is a waste of the pressure energy for CNG. For utilizing of the pressure energy, this paper promotes a method that applies regenerative multi stage valve piston expanders to recycle the high pressure CNG energy power translated into electricity. It is estimated that the efficiency of the expander system under this technology is more than 55%, the power storage and utilization efficiency is more than 90%, and the overall CNG pressure energy recycling efficiency can reach more than 50%.
