    Abstract

    This paper proposes static and dynamic Volt Amp Reactive (VAR) planning based on the active and reactive power profile enhancing for dynamic voltage stability of distribution networks with Battery Energy Storage System (BESS) and capacitor bank using VAR planning scheme on distribution networks. Firstly, the impact of dynamic high impedance and resistive non-linear loads in the static voltage stability of the system has been studied and the effects of complex load behaviour on system dynamical performance is presented through a system stability analysis for three network structures. A VAR planning method is proposed where active and reactive loadability (P-Q) is considered to analyse the vulnerability of the network to voltage collapse and system inefficiency. Compensating devices are placed considering P-Q loadability to improve system voltage profile and stability limit. Finally, a cost-effective combination of BESS and capacitor bank is determined through static and dynamic analysis to ensure voltage stability of the network. The results show that the proposed approach can reduce the required sizes of compensating devices which reduces costs, enhances the voltage regulation of the system and minimizes power losses.
