There is a master controller which is a website built with Ajax software to communicate with all the building devices (via a wireless router) which connected to Wi-Fi nodes (ESP8266 nodes) to calculate the consumed energy from each device and compare it with the fluctuated produced energy. The system is designed to keep the consumed energy, lower than the produced energy. This can be achieved by making the user take the decision and divides the building devices into three different priorities (High, Medium and Low). The presented system follows a strategy to reduce the load according to the available power and the device priority.

Li-ion of necessity must be controlled pending operation to be in a safe position and get the best performance, so it must be utilized battery management system (BMS). BMS functionality monitors, controls, and protects the battery pack from over-discharge, active balancing cells, and over-temperature. This paper proposed the charging method built on the fuzzy logic controller (FLC) to set the reference charging current through SoC of cells, also designed discharge controller via FLC to maintain discharge under limiting manufacturing rate with high protection for the battery string. The simulation results illustrate that protection features were the best performance. The proposed charging and discharging methods maintain the battery life cycle because, in charging, the temperature increase impacts the performance; this method change charge current value and in discharge also the effect of rising temperature reduce battery life cycle, this method has given discharge current depending on SoC and TMAX in the pack.

However, due to a rise in the oil's price on the international market, toxic pollution from burning oil, high maintenance costs, and short lifespans have been challenged to create more viable alternatives. Renewable energy can limit the use of fossil fuels, particularly by using the solar-powered water pumping system. This article aimed at finding an optimal design for a direct-coupled photovoltaic water pumping system in Iraq. The article presents the significant design aspect for an optimal system, such as the groundwater aquifer depth, installation aspect, cost, and irrigation efficiency. The design offers a combination of sprinkler and environmentally sustainable and cost-effective photovoltaic technology to reduce electricity and water use. A deep well to the storage system...

It is based on Proteus which is easy to use and common software among the electrical and electronics engineers. The aim of this paper is to describe a detailed mathematical model and how can it be implemented to study the different responses of the nonlinear photovoltaic array system behaviour. It offers a comprehensive model to measure the photovoltaic array output under any conditions based on the standard test conditions and the environmental parameters.

Besides, li-ion batteries require a safe and secure ground to reach the best performance and decrease the explosion risk. The safe operation of the battery is based on the main protection features and balancing the cells. This study offers a battery BMS design that protects li-ion batteries from overcharging, over-discharging and overheating. It is also offering passive cell balancing, an uninterrupted power source to load, and monitoring data. The used controller is Arduino mega 2560, which manages all the hardware and software protection features. Software features that include 1) variable charging speed according to the batteries charging status, 2) measuring the batteries state of health and state of charge, 3) controlling the uninterrupted driver, 4) regulating the charg...

The limitations and performances of WiMAX network have been considered for designing and then simulated by using OPNET, which based in this paper on many quality of services QoS parameters such as voice-packet end to end delay, as well as throughput. A simulation concentrated on two applications Light video, and heavy video at a square area and simulation time of about five minutes depending on multiple scenarios of WiMAX. A comparison made between WiMAX PCM voice with light video and heavy video data transmissions based on voice delay and throughput and shows the voice with heavy video has a delay less than the delay of voice with light video and the heavy video has larger throughput than light video.

The increment of salinity of the Shatt-Al-Arab river, the main source of the drinking water in this city, effected by the gulf water caused a lack of drinking water. What made matters worse is the frequent power outages caused by many reasons, one of these reasons that Basra considers one of the highest temperature cities in the world. For that, it is required to design an efficient device to harvest the water from the air to reduce the humidity and consider as a source for drinking water, taking into consideration it’s adopting a renewable source of energy. This article is presenting a low cost, portable, power-efficient, multi-purpose device that able to harvest water from the air efficiently. The results show a promising prototype that able to reduce significantly the relati...

The statistics of previous energy production and consumption of a case study city are used in providing the strategy. In the design of the proposed system, home appliances are categorized into three levels of priority, even though it can be more than three. In this article the control of energy consumption is achieved using a real time energy consumption manager (ECM) based on stored data without the need for real time communication. The system which is proposed here is affordable and simple. Also, it does not require grid upgrade or power line communication through the grid.

Soiling causes faults in the PV panels leading to a dras-tic reduction in the system efficiency. In vast solar PV farms, the detection of faults in an individual PV panel is a difficult task since it is usually done manually. In this research, a new design is proposed to detect the production of individual PV panel automatically and periodically to evaluate the condition of each panel in the farm no matter how it is connected in the array. The proposed design allows the user to measure the open circuit voltage (VOC), the short circuit current (ISC) and the delivered power for each PV panel in the farm. It is also capable of controlling each panel to work at the maximum power point using a built in Maximum Power Point Tracking (MPPT) sub-circuit on each solar panel. The presented system depicts a complete wireless sensor network, which does not need any extra wiring and is character-ized by being of ...
