Modeling And Control Of A Standalone Photovoltaic Using Fuzzy Based Perturb And Observe Maximum Power Point Tracking Controller For Water Pumping Application: (Case Study At Koka, Ethiopia)

Abstract

The Need For Energy Has Been Growing Daily In Recent Years, And PV Has Received More Attention Because This Energy Source Is Dependable And Extremely Efficient. The Difficulty In The Power System Is Growing As A Result Of Power Fluctuation In The Transmission And Distribution Systems, Power Quality Disturbances, And Major Blackouts, Which Can Lead To Notable Differences In Voltage And Network Frequency And Instability In The Systems. The Power Supply From Ethiopia's Electric Utility Is Also Insufficient, Which Makes It Difficult To Maintain Service Continuity For The Water Pumping In Irrigation System At Koka. The Standalone PV System Control Along With System Components Therefore Required.Additionally, The Maximum Power Point Tracking (MPPT), PV Panel, DC-DC Boost Converter, Inverter, LC Filter, And Three Phase Induction Motor Were Taken Into Account As Parts Of The PV System. The Site That Was Chosen Has A 67.52kwh Energy Consumption. Thus, CSS-MSP-250W PV Panel Was Selected Based On The Irrigation System's Energy Demand. To Regulate The Imbalance And Variation Of Energy And Maintain The DC Link Voltage At 400V, The PV Is Controlled Using A Fuzzy Enhanced P&O MPPT Algorithm. The THD Analysis Has Been Done With And Without LC Filter And Its Result Are 13.56% And 53.54% Respectively. This Show That There Is Almost 40% Minimization Of Harmonics At The Output Of Inverter. The Cost Of The Equipment Employed In The Proposed System Has Also Been Studied. Accordingly, The Net Present Cost And The Cost Of Energy Were $8,201.9 And $0.20/Kwh Respectively Which Is, Reliable And Efficient.
