印度Suzlon公司寻求日企合作开发海上风电市场

正据彭博社报道,印度风电机组制造商Suzlon可能会寻求日本企业合作研发海上风电机组,因为日本对于海上风电机组项目可以获得低息日元贷款。Suzlon旗下的德国公司Senvion是目前全球海上风电机组第三大供应商,8月20日前后,Suzlon总裁Tulsi Tanti在一个采访上表示,Senvion正在与日本公司洽谈合作,计划成立一个合资公司。Tulsi Tanti表示,海上风电机组研发是资产密集型产业,需要利用最低资金成本。至于目标市场,他表示日本和美国都是,因为日本今年也出台了一项有吸引力的海上风电电价机制。

Development of a flaw evaluation handbook of the high pressure institute of Japan

This paper introduces a handbook, which is edited by the High Pressure Institute of Japan to support engineers who evaluate flaws detected in nuclear power components according to the Japanese fitness-for-service code. The handbook is written in Japanese and contains basic information on fracture mechanics as well as the specific flaw evaluation procedures and material properties data stipulated in the code. The main features of the handbook are summarized in the paper.     

DSM in an area consisting of residential,commercial and industrial load in smart grid

With the latest introduction of the demand side management (DSM) in smart grids, the power distribution units are able to modify the load schedules of the consumers. This involves a co-operative interaction of the utility and the consumers so as to achieve customer load modifications in which the customer, utility and society all are benefited. The interaction is performed with the help of the devices known as the smart meter. This paper shows the use of game theory and logical mathematical expressions in order to achieve the objectives. The objectives are to minimize the peak to average ratio (PAR) and the energy cost. The outcome of the game between supplier and customers helps to shape the load profile. The design proposed in this paper is very user-friendly and is based on simple logarithmic programming computations. In this paper, residential, commercial and industrial types of loads are taken into account. A basic 24 h load schedule along with the fluctuating prices at each hour of the day is forecasted by the supplier of the various shiftable and non-shiftable loads and then that schedule is conveyed to the user. The users are encouraged to shift their high load devices to off-peak hours which will not only reduce their electricity costs but also substantially reduce the PAR in the load demand.

Electricity liberalisation in Europe—how competitive will it be?

All the countries of Western Europe have taken steps to liberalise their electricity industries. Large consumers in every country can choose their electricity supplier, and in some countries, this choice has been extended to every consumer. The European Union has decided that from 2007 at the latest, all customers will be able to choose their electricity supplier. A number of large European electricity companies have been responding to this changing environment by merging with electricity companies in other countries. This means that while some national markets may not look unduly concentrated, concentration at the European level has been growing. This paper addresses the reasons for this, and asks whether the resulting industry structure will be sufficiently competitive to deliver gains from liberalisation.     

Residual shape risk on natural gas market with mixed jump diffusion price dynamics

This paper introduces residual shape risk as a new subclass of energy commodity risk. Residual shape risk is caused by insufficient liquidity of energy forward market when retail energy supplier has to hedge his short sales by a non-flexible standard baseload product available on wholesale market. Because of this inflexibility, energy supplier is left with residual unhedged position which has to be closed at spot market. The residual shape risk is defined as the difference between spot and forward prices weighted by residual unhedged position whose size depends on the shape of customers’ portfolio of a given retail energy supplier. We evaluated residual shape risk over the years 2014–2018 with a real portfolio of a leading natural gas retail supplier in the Czech Republic. The size of residual shape risk in our example corresponds approximately to 1 percent of the profit margin of the natural gas retail supplier.     

Multiobjective environmental/techno-economic approach for strategic bidding in energy markets

This paper describes a method for developing optimal bidding strategy based on a bilevel optimization, considering suppliers’ emission of pollutants. The proposed methodology employs supply function equilibrium (SFE) model to represent the strategic behavior of each supplier. Locational marginal pricing mechanism is also assumed for settling the market and calculating the supplier profit. It is modeled as a bilevel optimization problem in which the upper-level subproblem maximizes individual supplier payoff and the lower-level subproblem solves the Independent System Operator’s market clearing problem. In this paper, the multiobjective optimal power flow is used to solve market clearing mechanism with supplier emission of pollutants, as extra objectives, subject to the transmission limits and supplier physical constraints. To illustrate the proposed approach under different conditions an IEEE 30-bus test system together with a number of case studies are used.     

Technical application of fracture mechanics to thin-walled structures

This paper reviews recent developments in the application of fracture mechanics to such structures as welded steel tanks, ships, and thin-wall pressure vessels, with particular attention to Japanese work. It describes methods for estimating critical crack size and safe working conditions, taking into account such fabrication variables as angular distortion, welding residual stress, prestrain, plate curvature and stress concentration. Whilst most of the paper is devoted to a consideration of the conditions for crack instability, it also discusses crack arrest and gives experimental results for the effect of thickness on both initiation and arrest.     

Recent Japanese research activities on probabilistic fracture mechanics for pressure vessel and piping of nuclear power plant

This paper describes a review of recent Japanese activities on probabilistic fracture mechanics (PFM) analyses. Japan Atomic Energy Agency (JAEA: previously JAERI) had sponsored research committees on PFM organized by Japan Society of Mechanical Engineers (JSME) and Japan Welding Engineering Society (JWES) for more than a decade. This work still continues with the same members in JWES. The purpose of the continuous activity is to provide probabilistic approaches in several fields of integrity problems of nuclear power plant. This paper shows some of the newest results of the JWES research committee. First topic is evaluation of the new JSME code case with rules of Fitness-For-Service from the view of PFM, including reactor pressure vessel subject to pressurized thermal shock loading, piping with a crack of the allowable size and effect of sizing accuracy for piping integrity. The next one is development of new PFM techniques including reliability assessment of piping with domestic (Japanese) SCC data and maintenance optimization of LWRs based on risk and economic models. The last topic is the international round robin program just starting from 2008.
