Energy management in grid-connected Micro-grids (MG) has undergone rapid evolution in recent times due to several factors such as environmental issues, increasing energy demand and the opening of the electricity market. The Energy Management System (EMS) allows the optimal scheduling of energy resources and energy storage systems in MG in order to maintain the balance between supply and demand at low cost. The aim is to minimize peaks and fluctuations in the load and production profile on the one hand, and, on the other hand, to make the most of renewable energy sources and energy exchanges with the utility grid. In this paper, our attention has been focused on a Rule-based energy management system (RB EMS) applied to a residential multi-source grid-connected MG. A Microgrid model has been implemented that combines distributed energy sources (PV, WT, BESS), a number of EVs equipped with the Vehicle to Grid technology (V2G) and variable load. Different operational scenarios were developed to see the behaviour of the implemented management system during the day, including the random demand profile of EV users, the variation in load and production, grid electricity price variation. The simulation results presented in this paper demonstrate the efficacy of the suggested EMS and confirm the strategy's feasibility as well as its ability to properly share power among different sources, loads and vehicles by obeying constraints on each element.

The Impact

Energy consumption in buildings is expected to increase by 40% over the next 20 years. Electricity remains the largest source of energy used by buildings, and the demand for it is growing. Building energy improvement strategies is needed to mitigate the impact of growing energy demand. Introducing a smart energy management system in buildings is an ambitious yet increasingly achievable goal that is gaining momentum across geographic regions and corporate markets in the world due to its potential in saving energy costs consumed by the buildings. This paper presents a Smart Building Energy Management system (SBEMS), which is connected to a bidirectional power network. The smart building has both thermal and electrical power loops. Renewable energy from wind and photo-voltaic, battery storage system, auxiliary boiler, a fuel cell-based combined heat and power system, heat sharing from neighboring buildings, and heat storage tank are among the main components of the smart building. A constraint optimization model has been developed for the proposed SBEMS and the state-of-the-art real coded genetic algorithm is used to solve the optimization problem. The main characteristics of the proposed SBEMS are emphasized through eight simulation cases, taking into account the various configurations of the smart building components. In addition, EV charging is also scheduled and the outcomes are compared to the unscheduled mode of charging which shows that scheduling of Electric Vehicle charging further enhances the cost-effectiveness of smart building operation.

Abstract The global pressing need to protect the environment, save energy and reduce greenhouse gas emissions worldwide has prompted the enterprises to implementing both individual energy saving measures and a more systematic approach to improve the overall enterprise’s energy performance. Energy management is becoming a priority as enterprises strive to reduce energy costs, conform to regulatory requirements, and improve their corporate image. As such, enterprises are encouraged to manage their energy related matters in a systematic manner and a more harmonized way, to ensure continual improvement on their energy efficiency. Despite the increasing interest in energy management standards, a gap persists between energy management literature and current implementation practices. The release of the ISO 50001 international standard was meant to help the organizations develop sound energy management systems and effective process-based energy management structures that could be recognized through third-party certification. Building on the energy management literature and energy management standards, the current paper presents the essential steps the enterprises should take to practically design a sustainable energy management system. Also, by using multiple case studies of enterprises that have implemented an ISO 50001 energy management system, it introduces a structured approach that companies can use to effectively develop their energy planning and improve energy performance. The key components of the enterprise’s energy planning are discussed, as well as practical examples of energy objectives and performance indicators from various industries are offered. The paper shows that by establishing an effective energy planning system, this will efficiently meet demands for achieving energy performance indicators and international certification.

Energy Management Systems

The term energy management from the past few years is becoming increasingly important. Not only the trend toward clean energy sources triggered a process of rethinking in the minds of society but also pushed the politics to create incentives for companies in order to make them reduce their carbon footprint. The efficient use of energy can be described as an integral part of current political, social and economic decision making.From a business perspective energy efficient production is no longer just considered under the ecological aspect. Through high taxes, huge energy costs and steadily increasing energy prices, there is for companies in the relatively young field of energy management enormous potential to financially improve and consequently save costs sustainably. Furthermore starting from 2015 the energy peak equalization law is made stricter, requiring companies to pay even more in taxes if they fail to fulfill all the requirements set by the politics.Hence the role of energy management systems (EnMS), which deal with the continuous and systematic improvement of the energy performance of businesses, is becoming increasingly important.This paper will deal with an energy management system that was developed by the Institute for factory automation and production systems at Friedrich-Alexander-University Erlangen-Nürnberg. The paper audits the proposed concept and checks it for consistency with the international energy management norm ISO 50001. Additionally all the corrections and necessary optimizations are made in order to provide the companies with a complete energy management system.The aim of this paper is to verify and check the EnMS concept which was developed in the institute for factory automation and production systems (FAPS) for its conformity with the International ISO 50001 standard. Thus ensuring the long term certification according to DIN ISO 50001.

Point Tracking

The microgrid vision has come to incorporate various communication technologies, which facilitate residential users to adopt different scheduling schemes in order to manage energy usage with reduced carbon emission. Through this study, we have introduced a novel method for residential load control with energy resources integrated. To this end, an input and optimization algorithm has been employed to control and schedule residential charges for cost savings, consumer inconvenience, and peak-to-average rate savings (PAR) purposes, including real-time electricity costs, energy demand, user expectations, and renewable energy parameters. This paper also provides a Maximum Power Point Tracking (MPPT) technique used to obtain full power from a hybrid power system during the variation of environmental conditions in both photovoltaic stations and batteries. An IEEE 14 bus program was considered to determine the efficiency of the proposed algorithm. This research also aims at developing the role model to determine the behaviors, as a result of a shift in the opening Protocol to the disconnect establishing the power generation island, of distributed energy resources on 14-node IEEE networks. The micro-grid is a simple case for the study of energy flow and smart grid efficiencyvariables and has dispersed tools. The findings show that the energy management system loadcollection using the suggested approach improves performance and decreases losses in contrast to previous approaches.
