“…The integration of renewable energy sources (RESs) into electrical systems has become a necessary and essential matter to face the large increase in electrical energy demand and reduce pollution problems caused by using fossil fuels. Different types of RESs are used in generating electric power, including wind, photovoltaic (PV), Fuel cell, and biomass [1][2][3][4]. The two most RESs integrated into the electrical systems are the wind and the PV in favor of their multiple advantages, which is evident from the annual growth rate of RESs, Fig.1, [5].…”

Connecting different renewable energy sources (RESs) to the electrical grids is presently being urged to fulfill the enormous need for electric power and to decrease traditional sources' ecological related issues, the so-called hybrid systems. Unfortunately, these hybrid systems suffer from the possible negative environmental impacts of the wind gusts in wind energy conversion systems (WECSs) that may degrade the overall system performance. Additionally, various severe faults may disconnect some RESs from the hybrid system, like three-phase faults. In this paper, the static synchronous compensator (STATCOM) is considered for both improving the performance of a hybrid system, contains WECS and photovoltaics (PVs) against wind gusts and maintaining the continuous operations of RESs during three-phase fault occur at the point of common coupling (PCC) between the RESs and the grid. The STATCOM is stimulated by two PI controllers regulating the reactive power flow between the STATCOM and the hybrid system at PCC and, consequently, regulating the voltage at PCC. A metaheuristic optimizer optimally schedules these two PI controllers based on whale optimization algorithm

“…A model was developed for estimating the energy production, selling electricity to the local grid using wind turbine (WT)/Hydrogen system, thermal recovery from fuel cells (FCs) [6]. The potential of both off-grid and on-grid PV, WT, FC, and biomass hybrid systems for the electrical energy generation with a focus on the optimal size of the GES has been inspected [7]- [14].…”

“…A detailed study about how to overcome the power outages in a rural area in Egypt by integrating a hybrid PV/WT/FC to the electrical utility was presented in [14]. This study focused on maximizing the profit from integrating these three GESs to the Egyptian electric utility considering the cost of these GES sources.…”

“…Power management in the hybrid AC/DC Microgrid is focused on droop and power flow regulation. Droop control can be used for both DC and AC sub-grids or both [11][12][13][14][15]. If the latter approach is used, an interlinking between the two sub-grids is mainly used to handle the case when any sub-grid failure occurs due to over-stress, keeping individual source variations as small as possible [9].…”

The problem of electrical power delivery is a common problem, especially in remote areas where electrical networks are difficult to reach. One of the ways that is used to overcome this problem is the use of networks separated from the electrical system through which it is possible to supply electrical energy to remote areas. These networks are called standalone microgrid systems. In this paper, a standalone micro-grid system consisting of a Photovoltaic (PV) and Wind Energy Conversion System (WECS) based Permanent Magnet Synchronous Generator (PMSG) is being designed and controlled. Fuzzy logic-based Maximum Power Point Tracking (MPPT) is being applied to a boost converter to control and extract the maximum power available for the PV system. The control system is designed to deliver the required energy to a specific load, in all scenarios. The excess energy generated by the PV panel is used to charge the batteries when the energy generated by the PV panel exceeds the energy required by the load. When the electricity generated by the PV panels is insufficient to meet the load’s demands, the extra power is extracted from the charged batteries. In addition, the controller protects the battery banks in all conditions, including normal, overcharging, and overdischarging conditions. The controller should handle each case correctly. Under normal operation conditions (20% < State of Charge (SOC) < 80%), the controller functions as expected, regardless of the battery’s state of charge. When the SOC reaches 80%, a specific command is delivered, which shuts off the PV panel and the wind turbine. The PV panel and wind turbine cannot be connected until the SOC falls below a safe margin value of 75% in this controller. When the SOC goes below 20%, other commands are sent out to turn off the inverter and disconnect the loads. The electricity to the inverter is turned off until the batteries are charged again to a suitable value.
