System Functioning

. A kind of energy storage proceeding from renewable sources is presented. It has been studied the storage, in the form of Compressed Air Energy Storage Systems (CAES) or Liquefied Air Energy Storage Systems (LAES) of the renewable electricity that, at the time it is generated, it is not delivered to the network because of technical or economic reasons, or saturation. The possibility of using an artificial storage system allows the installation not to be conditioned by the availability of a natural reservoir. This article focuses on the use of artificial storage systems, mainly for small power wind farms (about 30 kW), so storage systems will alternatively be called CAES or SCAES and LAES or SLAES (S from “small”) CAES systems advantages and disadvantages of each different thermodynamic cycle are studied. One of CAES systems higher limitations is the huge volume needed to store air mass enough. Instead of storing gaseous phase air, much more energy density can be accumulated by storing air in liquid phase (LAES). LAES system functioning is similar to CAES one. Liquid air is produced in an air liquefying plant when there is an excess of energy or it is not interesting to drop it into the network Some LAES systems advantages are storage volume reduction for the same energy density and the possibility of storing at about atmospheric pressure.

Farm Operators

Transmission system operators impose several grid-code constraints on large-scale wind farms to ensure power system stability. These constraints may reduce the net profit of the wind farm operators due to their inability to sell all the power. The violation of these constraints also results in an imposition of penalties on the wind farm operators. Therefore, an operation strategy is developed in this study for optimizing the operation of wind farms using an energy storage system. This facilitates wind farms in fulfilling all the grid-code constraints imposed by the transmission system operators. Specifically, the limited power constraint and the reserve power constraint are considered in this study. In addition, an optimization algorithm is developed for optimal sizing of the energy storage system, which reduces the total operation and investment costs of wind farms. All parameters affecting the size of the energy storage systems are also analyzed in detail. This analysis allows the wind farm operators to find out the optimal size of the energy storage systems considering grid-code constraints and the local information of wind farms.

Hybrid Renewable Energy System

The current paper presents an energy storage system that stores the excessive energy, provided by a hybrid system of renewable energy sources, in the form of compressed air and thermal heat. Using energy storage systems together with renewable energy sources represents a major challenge that could ensure the transition to a viable economic future and a decarbonized economy. Thermodynamic calculations are conducted to investigate the performance of such systems by using Matlab simulation tools. The results indicate the values of primary and global efficiencies for various operating scenarios for the energy storage systems which use compressed air as medium storage, and shows that these could be very effective systems, proving the possibility to supply to the final user three types of energy: electricity, heat and cold function of his needs.

The importance of energy storage systems is increasing in microgrids energy management. In this study, an analysis is carried out for different types of energy storage technologies commonly used in the energy storage systems of a microgrid, such as: lead acid batteries, lithium ion batteries, redox vanadium flux batteries and supercapacitors. In this work, it is analyzed the process of charging and discharging (slow and fast) in these systems, the calculation of energy efficiency, performance and energy supplied under different load levels, in its normal operating conditions and installed power capacity is developed. The results allow us to choose the optimal conditions of charge and discharge at different levels of reference power, analyzing the strengths and weaknesses of the characteristics of each storage system within a microgrid.
