The production of electrical energy has always been a subject of debate to fight against climate change and preserve natural resources. Several countries, including Morocco, have proposed ambitious policies to develop renewable energy sources of production in the short and medium term. The major problem of renewable sources production is their intermittent nature. Using storage units, particularly PETS' and molten salt technologies, will increase the penetration rate of renewable energies. The balance between production and consumption will optimize production, and it represents an important aspect of smart grids. In this article, an electrical energy consumption prediction was developed for the period 2019-2025, and optimization of the renewable energies injected within the grid was made by introducing the algorithm used. The results show that the use of storage units will increase the rate of renewable energies integration to 47.189% of the total installed capacity.

Overcoming the integration constraints of intermittent and predictable renewable energy production are one of the main distribution systems operators' objectives. Several solutions have been implemented and others are in the experimental phase, but most of these solutions are part of smart grid strategies. It is within this framework, that we have developed a solution that involves implementing a smart grid system downstream of the meter that will scratch onto the smart grid of the network manager upstream of the meter to complete it and give it a lot of flexibility. This system allows one to calculate the production forecasts of the renewable energy plants, to take charge of the load shedding priorities decided by the customer, to establish the optimal power supply scheme, to order the cut-off devices of the customer's internal installation for the execution of the optimal scheme, to communicate with the Distribution System Operator, to ensure compliance with its directives with regard to active and reactive powers to be injected on the distribution network by acting on the receivers and capacitors and responding to requests for deletion and making the necessary arrangements in such cases.
