Providing suitable conditions for the presence of humans is commonly the main cause for the energy consumption of buildings, but until now the movements of people to and from buildings are rarely taken into account by energy management systems. The arrival or presence of inhabitants is in some advanced systems recognized by location-based geofences or with on-site sensors, but not monitored in advance. This study aims to develop a dynamic concept that connects the real-time movement data of smartphone GPS sensors with building energy management systems. The novel concept uses the speed of movement of people towards or away from the building, the inertia of the controllable applications and the differential between the current state and set point as input for the energy management systems of the building. The purpose is to control energy applications before a person reaches the home, workplace or public space. In this way, optimal conditions in the space are available precisely when they are needed. The duration of the average daily commute of a person is in the same magnitude that is needed to activate devices that have inertia, for example, heating, ventilation or cooling.

The object of this work is designing a robust controller based on sliding mode technique of DFIG for using in wind turbine system. The conventional control of DFIG, such as vector control is very sensitive when the electrical and mechanical parameter are changed, to solve the problem of the vector control, the theory of sliding mode control is presented in brief, then it applied to the control of active and reactive power of DFIG. The simulation results prove that the implementation of the sliding mode controllers for active and reactive powerloops leads to good dynamic performance even with large electrical parameters change.

The problem of transmission network congestion or overloading poses a serious challenge to most power utilities around the world. One solution to this problem is the use of FACTS devices. This paper presents an empirical comparison of different optimal placement models of FACTS devices in a power system network with the objective to maximize the system loadability (SL). The three configuration are considered in this comparison. In the first case only TCPST is considered, while in the second case only TCSC is considered and in the third one a combination of several devices is considered. The results show that the first and the third configuration performs better economically and in terms of system losses.

Secondary Distribution Electrical Power Grid (SDEPG) is the last mile that connects end users. Dependency of communication network on the automation of SDEPG has raised the need to have High Availability (HA) communication network. Ensuring availability of communication network is essential for safe automation of SDEPG. Flexibility brought by Software Defined Networking (SDN) has made it possible to efficiently achieve HA communication network. Current literature reveals that SDN has commonly been deployed to achieve communication network resilience in primary distribution power grid which mostly use wired and leverages Internet Protocols (IP) layer only. Considering the nature of SDEPG, a combination of wired and wireless technologies is required, therefore a HA solution which cuts across all technologies and communication layers is required. In this paper a HA solution that considers both communication technologies and layer and leverages capabilities available in SDN is proposed. The solution also considers infrastructure challenges of both rural and urban areas.

The utilities around the world are facing a competition from renewable energy resources because of cheaper prices. A strategy to counter this problem is required. since the renewable energy resources are predictable especially solar energy, In this research a new dynamic tariff strategy was developed which will make electricity prices from the utility to be cheaper during the times when there are solar resources. The dynamic tariff strategy proved to be effective, the utility can counter the impact of renewable energy resources. This is done by offering cheaper electricity during the time when there are solar resources without losing the revenue.

The smart grid system can be integrated from different sources of renewable energy, such as photovoltaic panels, built by a large number of solar cells. The aim of this work is to study the influence of the single-diode model parameters on the current-voltage and power-voltage characteristics of the polycrystalline silicon photovoltaic (PV) cells. These parameters are series resistance, shunt resistance, and ideality factor. In addition the influence of the illumination and the temperature is examined. It was found that, the simulation results are acceptable; the model confirms that it is in agreement with the PV panel behavior as given by the manufacturer.

As an important renewable energy source in microgrid, photovoltaic (PV) generation has developed rapidly recently because of the merits of high flexibility and expansibility. But the partial shading from the trees, buildings or clouds easily appears in the large-area PV array system. In this paper, the partial shading impact on the PV array system is analyzed, and the results show that it will reduce the whole output power generation and the hard-shading fault will damage the stability of the PV system. In addition, it is analyzed that the parallel connection is much more advantageous than the series topology in partial shading situation, thus it is advised that the parallel connection should be adopted when the series voltage meet the requirement. Secondly, the hard-shading detection based on voltage sensor configuration is proposed and the hard-shading fault characteristics quantity is analyzed. Thirdly, according to the abovementioned fault feature, the backpropagation (BP) algorithm is adopted to locate the faulty position. Finally, the model is constructed in Matlab/Simulink circumstance to verify the analysis and the data is collected to verify the BP algorithm.

This paper presents an optimal control method for the energy management system to realize the introduction of renewable energy while maintaining and improving the energy service level in the private sector such as homes and offices. An energy system that combines solar power generation and storage battery charging / discharging can reduce the burden on electric power companies by optimizing the operation of the energy management system. Sustainable systems can be realized by applying economically optimal control methods. Applying the proposed demand-side energy management technology according to local power generation and demand conditions is expected to contribute to a wide range of energy and environmental problems.
