考虑绿色证书交易的寡头电力市场均衡分析

可再生能源配额和可交易绿色证书制度作为一种基于市场机制的新能源扶持政策,得到越来越多的关注。该政策的引入会对电力批发市场的竞争产生重要影响,特别是绿色证书交易市场与电力批发交易市场之间存在复杂的相互影响关系。为了定量研究该影响关系,采用寡头竞争均衡理论,建立了一个考虑绿色证书交易市场和电力批发交易市场的两阶段联合均衡模型。在第1阶段,可再生能源发电商以供应函数模式参与证书市场竞争;在第2阶段,所有发电商以古诺模式参与批发市场竞争。该模型描述的均衡问题可以表示为一个具有均衡约束的均衡问题,可采用非线性互补方法来求解。最后,算例仿真重点研究不同配额要求下发电商在两个市场中的策略性行为及相互影响关系,表明在不同的配额要求下,可再生能源发电商会选择在不同市场中行使市场力,并导致电力批发市场价格与绿色证书市场价格上升。     

基于有线电视网络互动付费增值系统的设计

提出了基于有线电视网络和移动支付平台实现互动业务付费的设计方案,如电视收视费预交、最新大片点播、电费、天然气费的代缴、酒店预定、医疗服务预约等.通过该系统平台,让用户足不出户就能享受多种服务,扩展了传统有线电视的功能.该系统平台采用流行的J2EE框架-Struts+Spring+Hibernate来架构,采用分层式结构,从而降低了系统的耦合性,提高了系统平台的健壮性.系统平台自上线以来运行良好,建设该系统平台为新形势下有线电视开展多种多样的增值业务服务提供了一个范例.

Market response to the public display of energy performance rating at property sales

Energy labels have generally received positive response from consumers and have moved the market for white goods and cars in the direction of more energy-efficient products. On the real estate market, it was expected that an energy label, rating the energy performance of a property based on a national energy performance certificate (EPC) might receive similar response. However, in Denmark no response to the energy performance rating was observed for 15 years. This was a surprise considering that Denmark was the first country to implement an A to G rating of the energy performance of buildings. A statistical examination of data on property sales prices and energy performance ratings was carried out. All relevant property transaction data from 2007 till 2012 were examined and they showed that energy performance ratings had an impact on property sales prices. However, before June 2010, the impact was modest, whereas after June 2010 the impact of energy performance ratings on property sales prices increased significantly as a result of an EU requirement to display the energy performance rating in connection with property sales. On this background, it was concluded that a public display of the energy performance rating is fundamental for market response.

Energy performance ratings and house prices in Wales: An empirical study

This paper investigates the effect of Energy Performance Certificate (EPC) ratings on residential prices in Wales. Drawing on a sample of approximately 192,000 transactions, the capitalisation of energy efficiency ratings into house prices is investigated using two approaches. The first adopts a cross-sectional framework to investigate the effect of EPC rating on price. The second approach applies a repeat-sales methodology to investigate the impact of EPC rating on house price appreciation. Statistically significant positive price premiums are estimated for dwellings in EPC bands A/B (12.8%) and C (3.5%) compared to houses in band D. For dwellings in band E (−3.6%) and F (−6.5%) there are statistically significant discounts. Such effects may not be the result of energy performance alone. In addition to energy cost differences, the price effect may be due to additional benefits of energy efficient features. An analysis of the private rental segment reveals that, in contrast to the general market, low-EPC rated dwellings were not traded at a significant discount. This suggests different implicit prices of potential energy savings for landlords and owner-occupiers.
