Many people reason as if electricity was accumulated in large tanks and that the operation of a swish was aquivalent to the opening of a tap .the reality is very different ,since electricity is not stored , at least in AC current as our networks are ,and therefore we must constantly ensure the balance between production and consumption. The fatal increase in load over the last few years has forced the state to invest in the electricity sector either by injecting new power plants such as TARGA’S largest powerplant in the west or building nes lines , such persists , which forces sonelgaz to find other solutions such as loadshedding or to improve the transited power as well as the economic distribution of power. For this we will focus on the study of the Algerien network,we will try to find the problems encountered related to theeconomis distribultion of powers in pratice. Subsequently, we will try to find solutions and we will try to find solutions and we will move towards therealization of the current renewable energy especially photovoltaic energyfrThesis
