Home Energy Management System

In this paper, we proposed a home energy management system (HEMS) that includes photovoltaic (PV), electric vehicle (EV), and energy storage systems (ESS). The proposed HEMS fully utilizes the PV power in operating domestic appliances and charging EV/ESS. The surplus power is fed back to the grid to achieve economic benefits. A novel charging and discharging scheme of EV/ESS is presented to minimize the energy cost, control the maximum load demand, increase the battery life, and satisfy the user’s-traveling needs. The EV/ESS charges during low pricing periods and discharges in high pricing periods. In the proposed method, a multi-objective problem is formulated, which simultaneously minimizes the energy cost, peak to average ratio (PAR), and customer dissatisfaction. The multi-objective optimization is solved using binary particle swarm optimization (BPSO). The results clearly show that it minimizes the operating cost from 402.89 cents to 191.46 cents, so that a reduction of 52.47% is obtained. Moreover, it reduces the PAR and discomfort index by 15.11% and 16.67%, respectively, in a 24 h time span. Furthermore, the home has home to grid (H2G) capability as it sells the surplus energy, and the total cost is further reduced by 29.41%.

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.
