Energy Storage Capacity

Wind power is one of the cleanest and safest of all the renewable commercial methods of generating electricity. However, wind energy is difficult to use due to its stochastic variability. Energy storage can overcome the main drawback, allowing energy production to match energy demand. In this paper a new method is proposed to determine the Energy-storage Capacity in Grid-connected Wind Farm. Based on characteristic function of wind power output in wind farm, the method designs the minimum required storage capacity of the wind farm and realizes the stable output and the scheduling of wind farm. The results of this paper demonstrate the leading role of a well-optimized design for technical and economic viability of such systems.

An important issue in the correct operation of the power system is the reliability of the electricity supply from generation systems. This particular problem especially concerns renewable sources, the output power of which is variable over time and additionally has a stochastic character. The solution used in the work to improve the reliability indicators of wind farm sources is the partial stabilization of their output power achieved through cooperation with the kinetic energy storage. Excessive increase in storage capacity is associated with a large increase in investment and operating costs. It is therefore important to determine the minimum storage capacity required to maintain the accepted criteria for the reliability of energy supply. In this paper, a population meta-heuristics algorithm was used for this purpose. The obtained results confirm the possibility of limiting the energy capacity of the flywheels, they also indicate its non-linear character as a function of selected parameters of the reliability of energy supplies from wind farms.
