考虑风险因素的两市场购电优化分配问题

不同国家和地区的电力市场通常根据自己的特点采用不同的市场模式,但无论在何种模式下,都存在一个类似于长期市场和短期市场的结构。电力市场中的购电商通常要在长期市场和短期市场进行电力交易,而其中的关键问题之一是如何针对本公司的情况,根据市场信息,寻求一种购电策略,优化两个市场的购电分配,使总的购电费用和风险尽可能得小。文中对这一问题进行了建模和讨论,针对由总费用和风险共同构成的目标函数,研究了两个市场的购电问题,给出了问题的解析解并针对实际市场数据进行了数值仿真,该问题的研究结果不仅有利于购电商分配不同市场的购电量,也为购电商进一步构造竞标曲线奠定了基础。     

绿色营销：变革、冲突与战略选择

绿色营销作为市场营销观念的革命在我国企业管理领域方兴未艾。通过论述绿色营销变革的基础与特征,从理论上阐明企业行为逻辑与绿色营销的内在冲突,提出了我国目前实施“政府主导型”绿色营销发展战略的构想。     

标准是市场调控的技术手段

论证了标准在市场调控中的作用,即是市场客体准入的通行证;是连接国内市场与国际市场的"技术平台";是调整产品结构、产业结构、社会供求的技术的依据.同时,分析了标准发挥市场调控的作用的三种实现形式.

Dynamic Testing of Wholesale Power Market Designs: An Open-Source Agent-Based Framework

In April 2003 the U.S. Federal Energy Regulatory Commission proposed a complicated market design—the Wholesale Power Market Platform (WPMP)—for common adoption by all US wholesale power markets. Versions of the WPMP have been implemented in New England, New York, the mid-Atlantic states, the Midwest, the Southwest, and California. Strong opposition to the WPMP persists among some industry stakeholders, however, due largely to a perceived lack of adequate performance testing. This study reports on the model development and open-source implementation (in Java) of a computational wholesale power market organized in accordance with core WPMP features and operating over a realistically rendered transmission grid. The traders within this market model are strategic profit-seeking agents whose learning behaviors are based on data from human-subject experiments. Our key experimental focus is the complex interplay among structural conditions, market protocols, and learning behaviors in relation to short-term and longer-term market performance. Findings for a dynamic 5-node transmission grid test case are presented for concrete illustration. This article is an abridged version of Sun and Tesfatsion ST07a     

多输出支持向量回归及其在股指预测中的应用

为了解决多输出回归问题，提出了一种新的多输出支持向量回归算法。给出了定义在超球上的损失函数，并将训练SVM转化为迭代解线性方程组，在求解过程中采用边计算边使矩阵降阶的方法，加快了运算速度。建立了该算法应用于股指预测的模型，对上证综合指数的建模与预测表明：与单输出支持向量回归算法建立的模型相比，该算法具有更好的整体预测精度和抗噪性能，是对证券市场进行分析和预测的一种可行而有效的方法。     

Agent-based simulation of electricity markets: a survey of tools

Agent-based simulation has been a popular technique in modeling and analyzing electricity markets in recent years. The main objective of this paper is to study existing agent-based simulation packages for electricity markets. We first provide an overview of electricity markets and briefly introduce the agent-based simulation technique. We then investigate several general-purpose agent-based simulation tools. Next, we review four popular agent-based simulation packages developed for electricity markets and several agent-based simulation models reported in the literature. We compare all the reviewed packages and models and identify their common features and design issues. Based on the study, we describe an agent-based simulation framework for electricity markets to facilitate the development of future models for electricity markets.
