[IEEE 2019 IEEE Electrical Power and Energy Conference (EPEC) - Montreal, QC, Canada (2019.10.16-2019.10.18)] 2019 IEEE Electrical Power and Energy Conference (EPEC) - Photovoltaic Array Reconfiguration to Reduce Partial Shading Losses using Water Cycle Algorithm

摘要： Partial Shading (PS) increases the power losses in Photovoltaic (PV) arrays significantly. Consequently, PS is considered one of the biggest challenges that face the operation of PV systems. PV arrays dynamic reconfiguration is a promising technique used to reduce PS losses. This paper proposes the Water Cycle Algorithm (WCA) as a new optimization technique for large PV array reconfiguration to reduce PS power losses. The execution time of the proposed algorithm is shorter than the existing algorithms when dealing with large PV arrays under irregular partial shading patterns.
