“…For example, Morocco has the goal to accomplish 52% of renewable energy by 2030 [1,2]. However, due to the unpredictability of renewable energy sources, it is not possible to use them autonomously without integrating energy storage systems [3][4][5]. Batteries are widely used in microgrids due to their ease of implementation and availability, making them the most common energy storage technology.…”

This paper investigates the design of a robust non-linear backstepping controller for the DC-AC microgrid comprising a photovoltaic source and a battery energy storage system with grid integration, all feeding a non-linear load, to improve its power quality and dynamic stability. A unidirectional DC-DC boost converter and a bidirectional back boost converter are used on the DC side to connect the photovoltaic module and battery storage to the DC bus. The three phases of the voltage source inverter are connected to the electrical grid via an inductive filter on the AC side. The control objectives are fourfold: i) Produce the maximum power from the photovoltaic system regardless of variations in weather conditions (temperature and irradiation); ii) Keep the DC link voltage constant and close to a given reference value under various conditions to ensure a balance of power between the DC and AC sides; iii) Active power control by injecting excess power into the grid; iv) Propose an energy management strategy to optimize the energy consumption of each source: the solar source, the grid, and the battery storage. Simulation results under different operating conditions, parameter variations, and load disturbances are presented and discussed to verify the performance satisfaction of the proposed controllers. An improvement in the overall dynamic performance of the microgrid is demonstrated, with a reduction in voltage overshoot (4.8%) and settling time (5.6ms) on the DC bus, along with reduced total harmonic distortion (THD) in grid current (0.29%) when compared with the other controllers in this work: the proportional integral controller (voltage overshoot (5.8%), settling time (15.5ms); grid current THD (6.53%)) and sliding mode controller(voltage overshoot (4.6%), settling time (15ms), grid current THD (3.53%). finally, several tests have been conducted on the proposed microgrid to evaluate the controller's efficiency in maintaining power balance during irradiation distortion and non-linear load imbalance.

“…In [18], it has been suggested that economic deployment of storage, used for the provision of peak capacity, could provide a substantial resource to reduce variable generation curtailment and increase variable generation penetration. In [19], safe integration of renewable along energy with energy storage devices has been discussed to have a reliable and efficient sustainable energy system. In [20], the DTR has been used to reduce the system costs and wind energy curtailment, and the ESS has been used to optimise the system costs but not for RES curtailment.…”

“…As already mentioned, energy storage system (ESS) can be generally used for solving the intermittent behaviour of RESs [16][17][18][19][20]. The ESS devices store the surplus produced energy of RESs in off-peak periods and can inject energy when it is needed [16].…”

In this study, new technologies such as dynamic thermal rating (DTR) technology and energy storage system (ESS) are simultaneously used to optimise the integration of renewable energy sources (RESs) and minimise the load shedding. For achieving the mentioned aims, a new method is proposed to select the candidate lines for the implementation of DTR technologies. The DTR technology is responsible for increasing lines limited capacity. Moreover, optimally placed and sized ESSs save RESs generated power in non‐peak‐hours and inject it to the network in peak hours. For validating the performance of the proposed solution, comprehensive simulations are performed in several stages on IEEE RTS‐24‐ and 30‐bus test systems networks. To meet the increased power demand, RESs (wind and solar) are optimally allocated by using the genetic algorithm (GA) in the test systems. Then, ESS devices are optimally sized and placed by using GA. Finally, candidate lines are selected based on the proposed method and DTR devices are added to the systems. Comprehensive comparisons are presented for comparing the previously presented solutions and the proposed one. It is proved that using DTR technology and ESSs along with the proposed line selection method is the superior solution for system operators.
