Batteries play an important role in stand-alone two-stage converter (boost converter and inverter) based solar photovoltaic (SPV) systems. Here, the maximum power point tracking (MPPT) operation of a stand-alone solar system is carried out with the usage of a battery by absorbing excess solar power. Nevertheless, instability (abnormal rise of DC link voltage) can appear during the real-time operation of the battery-based solar energy conversion system due to the action of the MPPT controller, if a sudden battery breakdown happens. In this respect, a failure detection-less solution is proposed. The suggested strategy restricts operation of the MPPT and helps to settle the output power of the SPV at non-maximum level on its P-V curve as per necessity. Thus, voltage instability at DC bus (link between boost converter and three-phase voltage source inverter [VSI]) is prevented. Here, the bus voltage can be kept within a predefined upper and lower limit. The limits are decided accordingly to the SPV characteristics. Simultaneously, the required load powers (both active and reactive portions) are supported by the VSI. In the proposed strategy, the output of the MPPT algorithm is restricted by adopting a saturation limit for a certain duty ratio. The critical task is to find the value of the saturation limit, as the limit supports all-time operations (it allows desired performances under all maximum power situations and avoids instability under all non-maximum operating conditions). The procedure of determining the limit is thoroughly described. The conventional approach uses a failure detection-based separate control algorithm. At the same time, the proposed concept does not require a separate algorithm. The suggested concept is validated via a MATLAB-SIMULINK-based simulation study and down-scaled experimental set up.

“…Nesse contexto, os conversores POL possuem como objetivo fornecer um nível de potência à uma carga específica, operando em uma faixa de tensão de entrada prédeterminada (CHERNAYA et al, 2016). Essas topologias geralmente possuem uma resposta rápida a transientes de carga e utilizam de técnicas de posicionamento adaptativo de tensão para reduzirem as perdas, uma vez que o circuito trabalha com baixos níveis de tensão e altos níveis de corrente (YAN et al, 2013).…”
