Evolutionary game-based optimization of green certificate-carbon emission right-electricity joint market for thermal-wind-photovoltaic power system

With the increasing proportion of renewable energy in the power market,the demands on government financial subsidies are gradually increasing.Thus,a joint green certificate-carbon emission right-electricity multi-market trading process is proposed to study the market-based strategy for renewable energy.Considering the commodity characteristics of green certificates and carbon emission rights,the dynamic cost models of green certificates and carbon rights are constructed based on the Rubinstein game and ladder pricing models.Furthermore,considering the irrational bidding behavior of energy suppliers in the actual electricity market,an evolutionary game based multi-market bidding optimization model is presented.Subsequently,it is solved using a composite differential evolutionary algorithm.Finally,the case study results reveal that the proposed model can increase profits and the consumption rate of renewable energy and reduce carbon emission.

A DRM System Based on Mobile Agent for Digital Rights Redistribution

We propose a digital rights management （DRM） system based on mobile agent to protect the copyrights of content providers. In the system, the content provider creates a time limited blackbox out of an original agent and dispatches it to the user end to enforce DRM functions. The blackbox is an agent that can resist the attacks from the malicious user in a certain time interval. Owing to digital rights redistribution support, the user whose rights belong to redistribution category can transfer his rights to other users. Moreover, by introducing public key infrastructure （PKI） and certificate authority （CA） role, the security of the session can be ensured. An analysis of system security and performance and a comparison with traditional DRM system is given.

A collaborative approach to integrated energy systems that consider direct trading of multiple energy derivatives

The cooperative model of a multi-subject Regional Integrated Energy System(RIES)is no longer limited to the trading of traditional energy,but the trading of new energy derivatives such as Green Certificates(GC),Service Power(SP),and CO_(2) will be more involved in the energy allocation of the cooperative model.This study was conducted for the multi-entity RIES cooperative model considering the trading of electronics,GC,SP,and CO_(2).First,a cooperative framework including wind-photovoltaic generation system(WG),combined heat and power system(CHP),and power-carbon-hydrogen load(PCH)is proposed,and the mechanism of energy derivatives trading is also analyzed.Then,the sub-models of each agent in the cooperative model are established separately so that WG has the capability of GC generation,CHP has the capability of GC and CO_(2) absorption,and PCH can realize the effective utilization of CO_(2).Then,the WG–CHP–PCH cooperative model is established and equated into two sub-problems of cooperative benefit maximization and transaction payment negotiation,which are solved in a distributed manner by the alternating directed multiplier method(ADMM).Finally,the effectiveness of the proposed cooperative model and distributed solution is verified by simulation.The simulation results show that the WG–CHP–PCH cooperative model can substantially improve the operational efficiency of each agent and realize the efficient redistribution of energy and its derivatives.In addition,the dynamic parameter adjustment algorithm(DP)is further applied in the solving process to improve its convergence speed.By updating the step size during each iteration,the computational cost,the number of iterations,and the apparent oscillations are reduced,and the convergence performance of the algorithm is improved.

Qualitative Comparison between the Brazilian Labeling Program for Buildings and the Portuguese Energy Certification System for Buildings:Proposals for Improving Brazilian Regulations

Buildings represent a significant share of the world’s energy consumption,and the sector has drawn the attention of governments,which have adopted policies to reduce energy expenditure.The Certifications of Energy Efficiency in Buildings stand out as one possible solution to achieve this goal,employed in several countries worldwide.The European Union presents advanced energy assessment programs for buildings,being a reference and model for several other regulations in the world.The Energy Certification System for Buildings(SCE)of Portugal is considered a success case,reflected in the significant number of energy certificates issued.The Brazilian Labeling Program for Building(PBE Edifica),first launched in 2009,does not find a broad application today in the Brazilian scenario.This work shows a synthesis of the European Energy Performance of Buildings Directive(EPBD)and the Brazilian and Portuguese regulations’history.A qualitative comparison is made between the SCE and the PBE Edifica to verify a European and a developing country’s regulations with a certain degree of cultural and climatic similarities.Through this comparison,proposals are made for improvements to Brazilian certification,seeking to improve its energy planning and energy policy concerning its building stock.The suggestions for improvement presented may also be appropriate for other developing countries that have started and have not yet successfully implemented their energy certification programs in buildings.

Introduction of Education Systems for Clinical Engineers in Japan

Japanese clinical engineer(CE) is a significant and unique profession compared with other nations with its dual clinical and technology focus and national licensing. The CE system of licensing was established in May 1987 under the Clinical Engineers Act. CEs are required to complete 3 to 4 years in designated schools and pass a national examination. It is a professional medical position responsible for the operation and maintenance of life-support and non-life-support medical device systems under the direction of physicians. Currently approximately 70 educational institutes- including technical colleges and universities- provide diverse and wide-ranging curricula from engineering to various clinical disciplines to produce CEs. Since clinical practice training is mandatory as a part of institute work, an important approach for CEs is gained by working in hospitals. The comprehensive curricula and the licensing system in Japan together serve to keep the appropriate quantity and quality of CEs. The Japan Association for Clinical Engineers(JACE) was established in February 1990; one of its aims is to support improvement of CEs throughout their careers through various lectures, seminars, on-the-job trainings, workshops, and an annual member meeting. New CEs can now take advantage of video e-learning. For junior CEs, there are seminars for hyperbaric oxygen therapy, blood purification, heart-lung bypass, respiratory therapy, operating room, intensive care unit, arrhythmia and aphaeresis related devices, as well as healthcare technology management(HTM). Also, the institutes provide a leadership seminar alongside this clinical practice training. Besides the licensing process, a proper certification system for CEs is a critical element in the clinical field. This enhances the ability of CEs to engage in more extensive duties and develop specialties, as well as to provide better healthcare. Associated societies provide certification with technology qualifications in dialysis, extracorporeal circulation, respiratory therapy, clinical medical devices, hyperbaric oxygen therapy, and aphaeresis treatment. JACE also launched a unique certification system in 2010, with specializations in blood purification, arrhythmia, respiratory, and hyperbaric oxygen care. What is the difference between certification by the associated societies and that offered by JACE? Certification by the associated societies provides basic knowledge to pass specialty examinations. Certifications by JACE promote deeper knowledge to enhance clinical decisionmaking and to encourage wider experience. JACE also continues to investigate other certifications. In summary, Japan has introduced a national licensing system for keeping an intake of constant quality and quantity of CEs. Additionally, ongoing workshops and seminars stimulate in-depth knowledge and a higher level of medical care for patients. Together, a system of lifelong education for CEs has been built.

Blockchain-Based Certificate Authentication System with Enabling Correction

Blockchain has proven to be an emerging technology in the digital world, changing the way everyone thinks about data security and bringing efficiency to several industries. It has already been applied to a wide range of applications, from financial services and supply chain management to voting systems and identity verification. An organization must verify its candidates before selecting them. Choosing an unqualified candidate can ruin an organization’s reputation. In this paper, a blockchain-based academic certificate authentication system will be used to ensure authenticity and make the assertion of the decentralized system secure. However, the system will generate, authenticate and make corrections on academic certificates. Ultimately, some blockchain-based authentication systems already exist, they can’t correct any errors that occur during generation. A blockchain-based certificate authentication system was built using blockchain technology. Where admin could generate, authenticate and correct the certificate if necessary. The admin can also check how many times a certificate has been modified. Other users can only check the authenticity of the certificates. We’re using two blockchains to enable corrections. Blockchain technology can successfully implement a certificate authentication system. This system will eliminate doubts about the authenticity of certificates, provide fast responses, and ensure reliable and secure storage. The proposed system will help in many ways, such as providing a user-friendly university admission, and smooth job hiring process, etc. In conclusion, our proposed system can permanently eradicate certificate forgeries and create and promote trust in society.

Modelling of Chillers for Energy Performance Assessment of HVAC Systems

The reliable assessment of the annual energy demand has become necessary in view of building energy performance certification. Accurate models must be used to simulate the behaviour of HVAC （heating, ventilation and air conditioning） components in real operation, usually characterized by a wide variation of building loads. In this context, this paper deals with the development and validation of an algorithm aimed at the assessment of part load performance of various kinds of controls for vapour compresion based heat pumps and chillers, in particular referring to on-off, inverter-driven and multi-stage vapour compression. The reliability of this algorithm in the calculation of seasonal performances is checked against monitoring of heat pumps and chillers operating under real conditions.
