... The state of hydroelectric water than used as a resource for electricity production which has a certain high and flow capacity. The generated electricity by this small plant depends greatly on the water discharge and the hight of the waterfall [16]. ...
... Solar PV systems come in a diversity of factors and a range of electricity generating capacities. At the first stage, the amount of total power that typically use and the number of hours of sunlight per day according to the location must be determined [9][10][11][12][13][14][15][16][17]. ...
... Figure 8 shows the power mode's shape. Figure 9 depicts the shape of a blocking diode used to prevent reverse current after sunset and ensure that no discharge from the batteries occurs (no batteries charging losses) [28], [29]. ...
Hybrid e-bike system is a bicycle included electric hub motor used to aid propulsion. A solar package with main components is built with it. This study included the travelled distance divided by time under only the batteries and batteries with photovoltaic (PV) modules (at different hours during the day). A comparison between two methods is made and documented in this paper. The paper aims to captivate the fettle and experiences with the use of e-bike. Commuting distance per hour was approximately 6.8 km/h. The current limitations must not exceed (10.4 A) and the big challenge, no shading plops on solar panels due to rider. Finally, depending on the solar irradiance with time curve, hybrid e-bike gave longer travelled distance with respect to time as compared with the batteries case study.
... In addition to the effect of load variation and change in the environmental condition. PV power system can't be connected to utility grid before eliminate the disturbance and improve the performance [10][11][12][13][14]. For this purpose, there are many suitable filters can be used such as L, LC and LCL according to the system requirements. ...
The Iraqi generated power less than loads requirements, these lead us to investigate and analyzing other energy resources to fill the gap between generated power and demand. Solar energy is more available and possible to use at the residential units for local loads and inject the excess power into the utility grid. In this paper, we present modeling and real-time analysis of the 1 2. 6kW Grid-connected PV system installed inside the solar energy laboratory at Northern Technical University. The study involved monitored data for march 2021 and the Simulink model used to analyze the performance of the PV system under non-uniform solar irradiance and grid disturbance. Particle swarm optimization algorithm (PSO) is adopted in the structure of the maximum power point tracking (MPPT).The obtained results evidenced that the system succeeds withstand different operational conditions and generate high quality power with the PV array efficiency of 17.4%, the MPPT efficiency 98.2%, and inverter efficiency 90.5%.
... Theoretical energy per day is 4,920 W h/day; the parameters given in Table 5 are used by the calculation of yield (performance ratio) [28][29][30][31][32][33]. Table 6 represents the calculation of PV modules number. ...
Global heating, depletions, and high cost of fossil fuels ensued the exploitation of AC sources of energy such as solar stamina. The peculiarities of photovoltaic PV module are a condition for dimensioning and designing a PV system. The causation for developing PV modules beneficial for electrical applications, this manner permits the development of new hefty-performances stand-alone PV system. PV ingredients are permitting the computation of the demeanor of the total system in medley scenarios. In this work, a comparison between calculation solar program and manual mathematical method are made according to Mosul-Iraq site.

This paper deals with the management of Energy Storage System (ESS) connected in a microgrid with a PV array and regulate the battery charge, hold and discharge operations using DC-DC bidirectional converter based on the requirement of the Load. The PV array along with the battery and load is simulated for various conditions such as PV supplying and charging the battery, PV supplying only the load, battery supplying the load and PV-Battery both supplying the load. The output parameters like voltage, current and power graphs are plotted and analysed for each condition. The entire paper is simulated on Matlab-Simulink environment.
The work presents in this paper is related to the proposal novel design and simulation of a dc to dc switching converter system suitable for charging a battery from a solar photo-voltaic (SPV) panel and a load controller circuit which is necessary to disconnect the load from the battery when the voltage of the battery falls below a certain value and to reconnect it again when battery charges. The load controller circuit disconnects the load from the battery in case the former draws higher than normal current from the battery. The charge controller section converts the varying voltage from the SPV panel to a constant voltage, current limited power to change the battery along with temperature compensation of the charging with constant voltage to ensure long life of the battery.
This paper presents a design and simulation of DC/DC boost converter. This system has a nonlinear dynamic behavior, as it work in switch-mode. Moreover, it is exposed to significant variations which may take this system away from nominal conditions, due to changes on the load or on the line voltage at the input. The input usually is obtained by PV array and therefore the design and simulation in this paper covers the whole range of radiations and temperature. In this paper we analyze the equations of a boost converter and propose a design components and simulation of DC/DC boost converter. This work is applied to photovoltaic system for tracking the point of maximum power.
A comprehensive supervisor control for a hybrid system that comprises wind and photovoltaic generation subsystems, a battery bank, and an ac load is developed in this paper. The objectives of the supervisor control are, primarily, to satisfy the load power demand and, second, to maintain the state of charge of the battery bank to prevent blackout and to extend the life of the batteries. For these purposes, the supervisor controller determines online the operation mode of both generation subsystems, switching from power regulation to maximum power conversion. Decision criteria for the supervisor based on measurable system variables are presented. Finally, the performance of the supervisor controller is extensively assessed through computer simulation using a comprehensive nonlinear model of the plant.
