Prospects and barriers analysis framework for the development of energy storage sharing

A Hybrid Model to Explore the Barriers to Enterprise Energy Storage System Adoption

“…Therefore, a "high initial setup cost" is one of the barrier factors for enterprises setting up energy storage facilities [29,32]. The steep costs for the setup energy storage equipment make the return on investment and the length of the payback period of the investment cost the focus of attention for financial executives, and if the enterprises are unable to confirm the management of the return on investment and the payback period for the equipment after purchase, this will affect the purchase decision [5,33]. Regular maintenance is indispensable to keep the equipment functioning properly, so the "maintenance cost" is of concern for business managers.…”

“…If the government could provide a national certification and standardization system for products, it would help enterprises to make purchasing decisions, especially when it comes to power supply and safety considerations. The lack of national certification and safety standards for energy storage equipment is thus a barrier to enterprise decisionmaking [5,36]. A complete energy management system must be able to integrate the enterprise's internal power supply, both dispatch and management, and energy storage equipment should not operate independently of the energy management system.…”

“…Suppose that s e ij is a full domain containing all objects (e.g., expert e evaluates the degree of influence of factor i on factor j). There are n factors in the full domain, and the lower approximate set of s e ij is comprised of all values equal to or less than s e ij in the full domain, as in Equation (4); the upper approximation set of s e ij is comprised of all values equal to or greater than s e ij , as expressed in Equation (5).…”

“…Today, under the encouragement of governmental policies, the technological development and application of renewable energy such as solar energy [2], wind energy [3], ocean thermal energy [4], and biomass energy [3] have become widespread, allowing for the diversification and utilization of varied sources of renewable power. Despite its non-polluting characteristics, renewable energy still has some disadvantages, such as unstable power quality and supply due to its randomness, intermittency, and volatility [5]. For example, the production of solar power is limited by the hours of sunlight, the sunlight intensity, the amount of cloud cover, and the wind speed [6,7].…”

A Non-Isolated High Voltage Gain DC–DC Converter Suitable for Sustainable Energy Systems

“…On the other hand, the scarcity of fossil fuels encourages people to develop utilization of green energy sources, such as PV, wind turbines, and fuel cells [2]. Photovoltaic sources are one of the essential methods for absorbing greener energy, accounting for most power generation among all renewable energy choices [3]. However, renewable energy output voltage and power levels are low and must be improved for many high-power applications [4].…”
