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...

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 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.
