Standalone Photovoltaic Power Stabilizer Using Double Series Connected Converter in Sudden Cloud Condition

Research output: Contribution to journalArticlepeer-review

Abstract

Renewable energy is clean energy that cannot harm the environment in its way, especially on standalone photovoltaic electricity generation. The only problem with renewable energy electricity generation is the intermittency and its instability in power quality and power efficiency. Power system stability in renewable energy is essential during the real environmental case problem such as the sudden cloud. The sudden cloud, known for its ability to decrease solar irradiance input, depends on how thick and big the cloud is. Several attempts had been tried to increase renewable energy power system stability, including modifying its maximum power point tracker with a new algorithm such as perturb and observe. This paper discussed an improved way of maintaining renewable energy power system stability using perturb and observe Algorithm in double series-connected Converter as the current and power stabilizer. The findings indicate that the abrupt cloud simulation reveals an undershoot current of 6,781 A at 500 W/m2, along with a steady-state current of 7,606 A. In a single converter scenario under sudden cloud conditions, there is a significant decrease of 3,416% in the steady-state current. Subsequently, in a dual converter setup, the reduction in steady-state current is demonstrated by an undershoot current of 6,781 A and a steady-state current of 7,606 A at 500 W/m2, corresponding to a decrease of 3,266%.
