Analysis and Modelling of Battery Energy Storage System for Smoothing Wind Power Fluctuation in the Case of Adama-II Wind Power Plant

Abstract

As a result of increasing proportion of renewable energy, more and more flexible options are necessary in order to flexibly compensate for the fluctuations regarding electricity generation through wind turbines power plants, consequently, a reliable power supply is guaranteed. One of the most prevalent forms of renewable energy is wind energy. It is a developing source of electric power generation because of its sustainability and advantages for the environment. When connected to the grid, the wind's sudden and unpredictable changes in speed make it an unpredictable and inconsistent supply of electricity, leading to various technical issues with protection, power quality, and generating dispatch control. Effective intermittent smoothing methods for wind power output are absolutely necessary to reduce these issues as a result of these issues. Battery energy storage system scheme is adopting to smooth wind power fluctuation and compensate power mismatch between wind power and desired power schedule for dispatching wind power on an hourly basis. In doing so BESS is modeled for Adama wind farm II of capacity 153 MW power. For first cluster of having 11 WT with 16.5MW power the battery capacity of 9.7MWh energy is modeled. Similarly for the left seven other clusters of having 13 WT with 19.5MW power each, the BESS capacity of 11.47 MWh is modeled. To track the power reference and MPPT in pitch angle control FPID Controller is implemented in Simulink
