Book Description
The design of maximum power point tracking (MPPT) techniques for standalone photovoltaic (PV) systems involves the development and implementation of strategies to optimize the power extraction from PV panels in off-grid or standalone applications. Standalone PV systems are commonly used in remote areas or places without access to the electrical grid, where they provide independent and sustainable power generation. The MPPT design techniques for standalone PV systems aim to address the challenges faced in maximizing the power output in varying environmental conditions, such as changing solar irradiance levels, temperature variations, and shading effects. These techniques focus on accurately tracking and maintaining the PV system's operation at the maximum power point (MPP) under dynamic conditions to ensure efficient energy conversion. There are various MPPT design techniques employed in standalone PV systems. These techniques utilize different control algorithms and strategies to continuously monitor the PV panel's operating conditions and adjust the system's operating parameters for optimal power extraction. Examples of MPPT design techniques include Perturb and Observe (P&O), Incremental Conductance, Fractional Open Circuit Voltage, and Model Predictive Control, among others. The design of MPPT techniques for standalone PV systems involves selecting the most appropriate algorithm based on the specific system requirements and characteristics. Factors such as algorithm complexity, tracking accuracy, convergence speed, stability, and robustness are considered in the selection process. The chosen MPPT technique should be capable of adapting to changing environmental conditions, compensating for PV panel degradation, and providing reliable and efficient operation in standalone applications. The design also encompasses considerations related to hardware implementation, including sensor selection, converter topologies, and control circuitry. Sensors, such as current and voltage sensors, are used to measure the PV panel's electrical parameters, while converters, such as buck, boost, or buck-boost converters, are employed to optimize the power transfer between the PV panel and the load or energy storage system. Furthermore, the design of MPPT techniques for standalone PV systems involves performance evaluation and optimization. Simulation models and experimental setups are used to assess the MPPT technique's performance in various operating conditions and load profiles. The objective is to maximize the energy yield, minimize power losses, and ensure reliable and efficient operation of the standalone PV system. In summary, the design of MPPT techniques for standalone PV systems involves selecting the appropriate control algorithm, optimizing hardware implementation, and evaluating the performance under different operating conditions. These design techniques aim to enhance the energy conversion efficiency, increase the power output, and ensure the reliable and sustainable operation of standalone PV systems in areas without access to the electrical grid.

Book Description
This book features cutting-edge research presented at the second international conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2018, held on 24–26 November 2018, at the High School of Commerce, ESC-Koléa in Tipaza, Algeria. Today, the fundamental challenge of integrating renewable energies into the design of smart cities is more relevant than ever. While based on the advent of big data and the use of information and communication technologies, smart cities must now respond to cross-cutting issues involving urban development, energy and environmental constraints; further, these cities must also explore how they can integrate more sustainable energies. Sustainable energies are a major determinant of smart cities’ longevity. From an environmental and technological standpoint, these energies offer an optimal power supply to the electric network while creating significantly less pollution. This requires flexibility, i.e., the availability of supply and demand. The end goal of any smart city is to improve the quality of life for all citizens (both in the city and in the countryside) in a way that is sustainable and respectful of the environment. This book encourages the reader to engage in the preservation of our environment, every moment, every day, so as to help build a clean and healthy future, and to think of the future generations who will one day inherit our planet. Further, it equips those whose work involves energy systems and those engaged in modelling artificial intelligence to combine their expertise for the benefit of the scientific community and humanity as a whole.

Book Description
Standalone (off-grid) renewable energy systems supply electricity in places where there is no access to a standard electrical grid. These systems may include photovoltaic generators, wind turbines, hydro turbines or any other renewable electrical generator. Usually, this kind of system includes electricity storage (commonly lead-acid batteries, but also other types of storage can be used). In some cases, a backup generator (usually powered by fossil fuel, diesel or gasoline) is part of the hybrid system. The modelling of the components, the control of the system and the simulation of the performance of the whole system are necessary to evaluate the system technically and economically. The optimization of the sizing and/or the control is also an important task in this kind of system.
