This research aims to provide such conditions in smart home applications, which monitor and control energy resources, in addition to evaluating the microgrid system whose function depends on economic strategies. MATLAB Simulink was built to manage home energy using the microgrid system. Measurements of the three signals represent that there was a decrease in energy consumption after using the Microgrid system. Two scenarios or cases were used to make a comparison of the performance after the addition of the PV array to the system. The electrical load is distributed in the late night and morning when the cost of energy purchased is minimum. At the same time, the daily production of energy by the PV is approximately around 4 MW in the interval between 6 am and 5 pm. The excess energy is stored to be used in the greatest power need periods (peak period). Some power may overflow during the day, and it can be sold to the local network at a certain price (usually less than the purchase price). Energy may increase during the day and overflow; in this case, part of it is sold to local networks at less cost than the purchase. Also, there is a reduction in the cost in the two previously mentioned cases from 1008.56 to -39.42 € due to the comprehensive management of the smart energy software by scheduling the use of electrical loads in the time windows between the start time and the end time according to change in price to get the minimum cost. In view of the use of (PV) and battery storage system, expenditure costs are also decreased, and the customer benefits from the surplus energy by injecting 26.66 kW into the grid and selling the surplus kilowatt to the local network as well.

Smart home energy management technologies (SHEMS) have long been viewed as a promising opportunity to manage the way households use energy. Research on this topic has emerged across a variety of disciplines, focusing on different pieces of the SHEMS puzzle without offering a holistic vision of how these technologies and their users will influence home energy use moving forward. This paper presents the results of a systematic, interdisciplinary meta-review of SHEMS literature, assessing the extent to which it discusses the role of various SHEMS components in driving energy benefits. Results reveal a bias towards technical perspectives and controls approaches that seek to drive energy impacts such as load management and energy savings through SHEMS without user or third-party participation. Not only are techno-centric approaches more common, there is also a lack of integration of these approaches with user-centric, information-based solutions for driving energy impacts. These results suggest future work should investigate more holistic solutions for optimal impacts on household energy use. We hope these results will provoke a broader discussion about how to advance research on SHEMS to capitalize on their potential contributions to demand-side management initiatives moving forward.

The Energy Storage System stores electricity for later use. This system can store electricity from legacy electric power systems or renewable energy systems into a battery device when demand is low. When there is high electricity demand, it uses the electricity previously stored and enables efficient energy usage and stable operation of the electric power system. It increases the energy usage efficiency, stabilizes the power supply system, and increases the utilization of renewable energy. The recent increase in the global interest for efficient energy consumption has increased the need for an energy storage system that can satisfy both the consumers` demand for stable power supply and the suppliers` demand for power demand normalization. In general, an energy storage system consists of a Power Conditioning System, a Battery Management System, a battery cell and peripheral devices. The specifications of the subsystems that form the energy storage system are manufacturer dependent. Since the core component interfaces are not standardized, there are difficulties in forming and operating the energy storage system. In this paper, the design of the profile structure for energy storage system and realization of private profiling system for energy storage system is presented. The profiling system accommodates diverse component settings that are manufacturer dependent and information needed for effective operation. The settings and operation information of various PCSs, BMSs, battery cells, and other peripheral device are analyzed to define profile specification and structure. A profile adapter software that can be applied to energy storage system is designed and implemented. The profiles for energy storage system generated by the profile authoring tool consist of a settings profile and operation profile. Setting profile consists of configuration information for energy device what composes energy saving system. To be more specific, setting profile has three parts of category as information for electric control module, sub system, and interface for communication between electric devices. Operation profile includes information in relation to the method in which controls Energy Storage system. The profiles are based on standard XML specification to accommodate future extensions. The profile system has been verified by applying it to an energy storage system and testing charge and discharge operations.

In this paper, we consider an Energy Consumption Scheduler (ECS) unit inside a smart meter. The function of ECS is to flatten the peaks in the load curve of residential type users. The ECS dually communicates with the user as well as power utility in smart grid real time communication environment. Each user has a specific power capacity limit for their appliances operation. The ECS keeps check and balance condition whenever a user exceeds its power capacity limit. Also the most urgent appliance operations are given priority based on their internal preemption state. By adopting ECS unit, the total peaks in the load curve are reduced up to 33.3%. Also the user's payment to the power utility becomes less due to efficiently managing their appliance operations. Additionally, the cost of per unit energy generation is also reduced by avoiding the peak power plants. Matlab/Simulink is used as a simulation tool for the realization of this model.

A significant role in obtaining a comfortable environment in a residential, office, factory or other public interest buildings is conferred in a large measure to the lighting and the heating. These two components through their efficiency can assure important benefits to the users of that environment. Estimating the lighting and heating efficiency can be achieved through attending the qualitative and quantitative indicators specific to the goal for which the lighting and heating system was designed. Based on these indicators one can design a system with the basic function of assuring and if necessary of adapting the lighting and heating hence of maintaining the indicated indicators to an optimal value. When the expected qualitative and quantitative values of the indicators cannot be obtained, the system must inform the executive of the system about the decrease of the building environment quality, with the object of making a decision to determine the rehabilitation acts of the components or the whole system. Beside the basic functions, the system aims to attach an optimizer module, which will supply the necessary information to make an optimal decision about lighting and heating system, taking other parameters into consideration, as well, different from the previous ones, such as energetic and economic parameters to obtain both energetic and also economic efficiency in buildings. The present paper presents the structure of a system based on intelligent technology and the benefits that can be achieved

This paper focuses on Demand-Side load Management applied to residential sector. A multi-scale optimization mechanism for demand-side Load management is proposed. It compose the Agent Management of Energy, it carries out the distribution of the energy of the housing by proposing a dynamical threshold of total energy consumption will be applied to each household. The home automation system integrated in each household plays the role of controlling all the energy consumption in the housing by using service flexibilities, which have the possibilities to be modified and controlled. Thanks to the feedback of the satisfaction of the client by the home automation system, the Agent Management can modify the limit of power consumption of the household again. This mechanism of control takes dynamically into account the comfort of the users and satisfies the constraint from the energy production capabilities. A simulation of 200 housings is also illustrated the performance of this control mechanism.

This paper focuses on demand-side load management applied to the residential sector. A home automation system controlling household energy is proposed. It is decomposed into three layers: anticipation, reactive and device layers. This paper deals with an anticipation layer that allocates energy by taking into account predicted events. It consists in computing both the starting times of some services and in determining set points of others while satisfying the maximal power constraint. A constraint satisfaction problem formulation has been proposed. Because the complexity is NP-hard, a tabu search is used to solve the problem. It maximizes user comfort and minimizes energy cost. An application example is presented

A successful energy management control system using a personal computer (PC) is developed in this paper to avoid wastage of energy by human carelessness. A small residential building model is considered and a PC is used as a tool to monitor the electrical system. Sensors are considered to monitor the number of persons entering or leaving and the computer system switch on/off the electrical equipment, and able to count the number of people in each room in the building. The system continue to count when more people enter the rooms. When all the peoples leave the rooms the system will switch off all the electrical equipments to make sure that there is no wastage of energy. This paper shows that energy savings is achieved in a building by having a proper interface using a PC with minimum hardware and software.

A neural fuzzy system controlling home appliances is proposed. The central goal of home automation is to provide an efficient and convenient integration and inter-operation among appliances in households. The necessary software tools should present a comfortable user interface. One suitable programming method for home automation systems is the definition of linguistic rules that can be processed by a fuzzy system. In our approach it is assumed that the home system adapts itself to the occupants' lifestyle. Based on this idea, we present an appropriate neuro fuzzy controller. An implementation of this artificial intelligent based controller under the MATLAB/SIMULINK development environment is shown. It consists of functions that upgrade MATLAB/SIMULINK to a tool with hardware and Internet access. This tool is not only restricted to home automation, it can also be applied to control non time-critical processes
