Research And Development Of The Evaluation Of Operation Economic In Transmission Grid

In electric market, one of the basic functions of the grid is to provide the services credible and high quality service un-discriminatorily, and take in the charge of the services, for example, the charge of using the grid, the charge of the dispatching service and the charge of exchange service. At the same time, it leads the power plants and the consumers to optimize the resources effectively by the reasonable price of transmission and distribution. So reasonable price of transmission and distribution, good quality of service and low cost of running is not only the basic way of ensuring the benefit of the grid, but also is very important to good-ordered, exuberance and persistent development of the whole electric market. So how to evaluate the status of the grid under the mechanism of the market is the key to decide the reasonable strategy, guide line for the grid and to exert the important use of the grid continuously. It is the basic guarantee for the taking charge organization to take charge of the grid, to decide reasonable price of transmission and distribution and to lead the persistent development of the electric market too.Aiming at the function and requirement of the grid and regulator under the mechanism of the market in the future, this paper put forward the concept, frame and method of the evaluation for economic benefit of the grid's operation, attempt to establish a set of guideline system that is applied to evaluate economic benefit of the grid's operation. In this paper it also design and realize the system of the evaluation. It can give powerful instruction to the grid under market in the future. At the same time, it can give reasonable proof for regulator to carry out right and effective taking charge measure.In this paper, we introduce briefly the role and the status of the grid in the electric market, analyse the economic character and behavior of the grid with nature monopoly.Upon this basic.this paper establish a set of evaluation guidelines to include all the side of the grid economic operation. These guidelines has used the directions guidelines for reference which the government used to evaluate the enterprise's economic benefit. This paper also sorts, delaminations and groups these guideline in order to make it reflect the status of the grid operation.At the same time,in view of the character of the economic evaluation in grid, this paper chooses the mature evaluation methods in the fields of engineering to evaluate the economic of the grid's operation.This paper also takes the analysis of basic and extend break-even.In the end of this paper,according the research ahead,this paper develops the software system and make the case study.
