Research on joint coordination control of stand-alone wind-solar systems with battery storage

摘要

This paper presents a power coordinated control strategy based on the maximum power point tracking (hereafter for MPPT) control, load power point tracking(hereafter for LPPT) and battery charging and discharging according to the relationship between the system energy flow and the operation condition of Wind-solar Systems with Battery Storage (hereafter for WSSBS), and the realization method was presented referring to practical data. We comprehensively construct stand-alone WSSBS and take the actual light and wind speed as the input. Finally, the feasibility of the power coordinated control strategy is tested under the condition of the random wind, the light intensity and the load in the MATLAB environment.
