Abstract: Energy conservation or energy saving is one of the most important methods for reducing CO2 emissions, which is known to be associated with global warming. Although development of renewable energy sources such as solar or wind energy is necessary, we must first pay attention to the fact that enormous amounts of energy are consumed uselessly at present. Energy saving should therefore be one of the first problems to be tackled. It may not only bring reductions in CO2 emission, but also may lead to savings in expenditure on energy. This paper introduces some of the initiatives taking place in Japan aimed at energy conservation.

Abstract: 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.

Abstract: In self-power sensor nodes, the capability of energy harvesting and storing of the solar micro-power system determines their lifetime and adaptability to the environment. As a load of solar cells, energy storage devices directly influence the output conversion efficiency of solar cells and output power of solar micro-power system. In this paper, the advantages and disadvantages of NiCD batteries, NiMH batteries, Polymer Lithium-ion batteries and Super-capacitors are analyzed based on features of the solar micro-power system. A hybrid storage system combined with Polymer Lithium-ion batteries and the super-capacitors is designed. Experimental results show that the power density of hybrid storage system is larger than that of Polymer Lithium-ion batteries. The capability of pulsing load is improved over 60%, and the energy storage loss is reduced.

Abstract: The usage of renewable energy systems increases worldwide due to extinction of conventional sources and also the absence of some serious environmental effects such as global warming, ozone layer depletion etc. These renewable power systems are not able to satisfy the load continuously due to seasonal availability of the resources. A Hybrid Power System (HPS) formed with renewable energy sources are a solution to provide power for stand-alone electrical loads. However, the energy management in HPS is quite complex as it relies on a central controller. This paper proposes a distributed Energy Management System (EMS) to control the energy flow in the PV/Wind/Fuel Cell/Battery HPS based on multi-agent system (MAS) technology. With this concept, a HPS is seen as a collection of different elements called agents, collaborates to reach a global coordination to satisfy the demand in the system. The Algorithm of the Multi-Agent System technique for HPS has been implemented using MATLAB/Simulink environment. The results show that the algorithm is effectively working for a HPS to provide power to the load and control power flow between various elements of the system.

Abstract: Hybrid electric vehicle was powered by motor and engine. So making a good energy management strategy to torque split between motor and engine is very important. A static control strategy is not suitable for all drive cycles and all driving habits. This paper designs an adaptive control strategy for parallel HEV. In order to regulate the SOC balance of batter, the adaptive control strategy can update itself through analyzing the data obtained from previous driving cycle. Adaptive control strategy was tested in driving cycle of BC_CTC, the result prove that this method is effective.

Abstract: An AMI platform for DG energy management is proposed to provide service both utilities and customers in this paper. By enabling the interactive and efficient communication platform, the proposed AMI facilitates utilities to perform the energy management of DGs, economic dispatch and demand response effectively. Base on the CIM model, OSGi platform leads the AMI extendibility and Interoperability. The communication network includes several advanced communication technology which are used in distributed systems, if the AMI for DG can share the communication network and smart terminal even some advance application software in the utility information platform, it will work more powerfully and effectively.

Abstract: By increasing the share of renewable energy sources, the volatility of available energy is rising. More and more fluctuating power generation by solar power plants and wind turbines has to be integrated into the power grid. Demand side management (DSM) represents one possible solution to achieve this goal by including energy production and energy consumption simultaneously. In this paper, we especially focus on the field of electric energy in smart homes. Considering the implementation of different DSM devices, an ontology-based approach can serve as a conceptual foundation for a necessary knowledge base. We propose an advanced energy ontology for smart homes, integrating important aspects for a successful DSM. We describe how power producers, storages and consumers are represented in our ontology. Finally, we show the scenario-based utilization of our approach.

Abstract: With the rapid development of economy and technology, enterprises in eco-industrial symbiosis network (EISN) are facing enormous challenges. However, the emergence and development of EISN is closely tied with the energy management in eco-industrial park (EIP). This paper takes institution construction, allocation and new technology of energy management, cooperation performance and long-term cooperation relationship into research and develops a theoretical model of energy management accordingly. We conduct statistical analysis and Structural Equation Modeling using SPSS17.0 and AMOS17.0 based on 241 valid questionnaires from the EISN enterprise managers. The findings indicate institution, allocation and new technology are significantly positively related to cooperation performance, and cooperation performance has positive significant influence on long-term cooperation relationship. Based on the above results, the relative strategies and suggestions of strengthening energy management to enhance cooperation performance are given.
