Microcontroller Based Maximum Power Point Tracking For Photovoltaic Solar Panel

Abstract

Many papers are published in the past and at present time which operate the solar photovoltaic (PV) panel at its maximum power point, by implementing an analogue or digital electronic circuits which are known as maximum power point trackers (MPPT). The main purpose of the researches are to obtain maximum power from the (PV) solar panel under different atmospheric conditions. In this paper a digital technique based on microcontroller type 8051 is used to design and implement the (MPPT) using maximum power point voltage method. The proposed (MPPT) consists of three major units (i) the solar (PV) panel (ii) the DC/DC step down inverter (iii) the control unit and computation of maximum power point based on microcontroller. ‫اﻟﺸﻤﺴﯿﺔ‬ ‫ﻟﻠﺨﻼﯾﺎ‬ ‫اﻟﻘﺼﻮى‬ ‫اﻟﻘﺪرة‬ ‫ﻧﻘﻄﺔ‬ ‫ﻣﺘﺘﺒﻊ‬ ‫ّﺮ‬ ‫اﻟﻤﺼﻐ‬ ‫اﻟﻤﺴﯿﻄﺮ‬ ‫ﺑﺎﺳﺘﺨﺪام‬ ‫ﺟﺎﺳﻢ‬ ‫ﻣﺤﻤﺪ‬ ‫ﻣﺼﯿﺐ‬ ‫ﺻﺎﻟﺢ‬ ‫ﻏﺎوي‬ ‫ﻛﺎﻣﻞ‬ ‫ﻣﺠﯿﺪ‬ ‫إﻟﮭﺎم‬ ‫رﺷﺎ‬ ‫اﻟﻤﻮﺻﻞ‬ ‫ﺟﺎﻣﻌﺔ‬ ‫اﻟﻤﻮﺻﻞ‬ ‫ﺟﺎﻣﻌﺔ‬ ‫اﻟﻤﻮﺻﻞ‬ ‫ﺟﺎﻣﻌﺔ‬ ‫اﻻﻟﻜﺘﺮوﻧﯿﺎت‬ ‫ھﻨﺪﺳﺔ‬ ‫ﻛﻠﯿﺔ‬ ‫واﻟﻐﺎﺑﺎت‬ ‫اﻟﺰراﻋﺔ‬ ‫ﻛﻠﯿﺔ‬ ‫اﻻﻟﻜﺘﺮوﻧﯿﺎت‬ ‫ھﻨﺪﺳﺔ‬ ‫ﻛﻠﯿﺔ‬ ‫ﺍﻟ‬ ‫ﻤﺴﺘﺨﻠﺹ‬ ‫ﻨﺸﺭﺕ‬ ‫ﺍﻟﺒﺤﻭﺙ‬ ‫ﻤﻥ‬ ‫ﺍﻟﻌﺩﻴﺩ‬ ‫ﻭ‬ ‫ﺍﻟﻤﺎﻀﻲ‬ ‫ﻓﻲ‬ ‫ﺒﺨﺼﻭﺹ‬ ‫ﺘﻨﺸﺭ‬ ‫ﺘﺯﺍل‬ ‫ﻻ‬ ‫ﻭﺘﺸﻐﻴﻠﻬ‬ ‫ﺍﻟﺸﻤﺴﻴﺔ‬ ‫ﺍﻟﺨﻼﻴﺎ‬ ‫ﺎ‬ ‫ﺍﻟﻘﺩﺭﺓ‬ ‫ﻨﻘﻁﺔ‬ ‫ﻓﻲ‬ ‫ﺍﻟﻘﺼﻭﻯ‬ (MPP) , ‫ﺍﻻﻟﻜﺘ‬ ‫ﺍﻟﺩﻭﺍﺌﺭ‬ ‫ﺘﺼﻤﻴﻡ‬ ‫ﺨﻼل‬ ‫ﻤﻥ‬ ‫ﻭﺫﻟﻙ‬ ‫ﻨﻘﻁﺔ‬ ‫ﻤﺘﺘﺒﻌﺎﺕ‬ ‫ﻋﻠﻴﻬﺎ‬ ‫ﺃﻁﻠﻕ‬ ‫ﻭﺍﻟﺘﻲ‬ ‫ﺍﻟﺭﻗﻤﻴﺔ‬ ‫ﺃﻭ‬ ‫ﺍﻟﺘﻨﺎﻅﺭﻴﺔ‬ ‫ﺭﻭﻨﻴﺔ‬ ‫ﺍﻟﻘﺼﻭﻯ‬ ‫ﺍﻟﻘﺩﺭﺓ‬ (MPPT). ‫ﺃﻗﺼﻰ‬ ‫ﻋﻠﻰ‬ ‫ﺍﻟﺤﻤل‬ ‫ﺤﺼﻭل‬ ‫ﻫﻭ‬ ‫ﺍﻟﺒﺤﻭﺙ‬ ‫ﻫﺫﻩ‬ ‫ﻤﻥ‬ ‫ﺍﻟﻬﺩﻑ‬ ‫ﻭﺘﺤﺕ‬ ‫ﺍﻟﺸﻤﺴﻴﺔ‬ ‫ﺍﻟﺨﻼﻴﺎ‬ ‫ﻤﻥ‬ ‫ﻁﺎﻗﺔ‬ .‫ﻤﺨﺘﻠﻔﺔ‬ ‫ﻤﻨﺎﺨﻴﺔ‬ ‫ﻅﺭﻭﻑ‬ ‫ﺍﻟﺒﺤﺙ‬ ‫ﻫﺫﺍ‬ ‫ﻓﻲ‬ ‫ﺍﻟﻤﺴﻴﻁﺭ‬ ‫ﻋﻠﻰ‬ ‫ﺍﻟﻤﻌﺘﻤﺩﺓ‬ ‫ﺍﻟﺭﻗﻤﻴﺔ‬ ‫ﺍﻟﺘﻘﻨﻴﺔ‬ ‫ﺍﺴﺘﺨﺩﻤﺕ‬ ‫ﺍﻟﺩﻗﻴﻕ‬ ‫ﻨﻭﻉ‬ (8051) ‫ﻟﺘﺼﻤﻴﻡ‬ ‫ﻭﺘ‬ ‫ﺍﻟﻘﺼﻭﻯ‬ ‫ﺍﻟﻘﺩﺭﺓ‬ ‫ﻨﻘﻁﺔ‬ ‫ﻤﺘﺘﺒﻊ‬ ‫ﻨﻔﻴﺫ‬ (MPPT) ‫ﺘﺘﺒﻊ‬ ‫ﻁﺭﻴﻕ‬ ‫ﻋﻥ‬ ‫ﺍﻟﻘﺼﻭﻯ‬ ‫ﺍﻟﻘﺩﺭﺓ‬ ‫ﻨﻘﻁﺔ‬ ‫ﻓﻭﻟﺘﻴﺔ‬ ‫ﻟﻠﺨﻠﻴﺔ‬ .
