| 摘 要： | 在基于市场机制的网格系统中，资源调价问题十分复杂。文章讨论了网格资源价格的二重性，局部最优价格和全局最优价格，根据网格资源的特征将资源划分为孤立资源和依赖资源，针对这两类资源的不合理价格提出了相应的调价策略。孤立资源的调价策略强调抑制资源的垄断价格和保护资源的最低价格，依赖资源的调价策略则强调消除资源局部最优价格和全局最优价格之间的矛盾，以获得能促进网格资源供求全局平衡的均衡价格。文章通过实例说明了本调价机制的有效性和实用性。

| Abstract: | In the market-oriented grid system,resource price-adjustment is challenging.Firstly,in this paper,we discuss two conceptions related to price-adjustment:"local optimization" indicating that the price of single resource is optimal and "global optimization" indicating that the prices of all resources are so equilibrious that the supply and demand of grid resources are globally balanced.Secondly,by analyzing the characteristics of grid resources,we divide Grid resources into two classes: "isolated resource" and "dependent resource",and propose a price-adjusting strategy that effectively solve the contradiction between local optimization and global optimization to achieve equilibrium price system.Finally,we illustrate the utility of the price-adjusting mechanism. |
