Connecting Renewable Energy Sources and Systems (RESSs) to utility power grids is one of the most ambitious endeavors of Smart Grid (SG) development in many countries. The challenge of integrating RESSs is that it is highly variable, intermittent and unreliable. Electric power grids must therefore absorb this variability with a portfolio of solutions. Today, we are already seeing strong signs of convergence in the development of the power grid in many developing and emerging countries, and the transformation of the energy system through the efforts of different stakeholders in this field: academia as well as large and small businesses, who continue to push the boundaries of knowledge in the energy sector. On the other hand, governments need to come up with policies that promote innovation while not jeopardizing the SG infrastructure. This article has been arranged to introduce the subject in the first section, the second section presents the concept of a SG, then we involve in the third section a case study for Moroccan SG roadmap and the problem statement related to legislative context, which considered as a major obstacle for SG transitions not only in Morocco, but in some other developing countries. Hence, the last subsection proposes an efficient strategy as a solution to overcome some specific issues even in technology or in regulatory, while the forth section was devoted to the conclusion.
