Informatization construction becomes an important task of today's power grid enterprises. In order to ensure the informatization implementation, to understand the impact factors of benefit and avoid reckless investment, a reasonable evaluation to the informatization investment efficiency of grid enterprise is needed. This article starts from building index system on the basis of fully understanding...
To speed up the construction of urban distribution network investment, a good way is to improve the reliability of grid power supply and the level of electric terminal safety. Electric power system is an organic whole, while urban distribution network has a large-scale investment. Under the constraint of total amount of investment, how to arrange the proportion of the investment between different...
Based on the in-depth analysis of urban network's characteristics, a comprehensive model composed of an evaluation index system and a novel evaluation methodology is described for studying environmental effects that planning schemes might cause if they were implemented. The novel model focuses on various typical perspectives, such as pollution emissions, carbon emissions and environmental coordination...
Power Plant Construction project plays a very important role in ensuring the national economic and social development, promoting industrial structure adjustment and optimizing the allocation of resources, while post project evaluation is a vital sector and link as well to test whether Power Plant projects achieve the construction goal and benefit effect. Through analyzing and research the existent...
This paper presents a multistage transmission expansion planning (TEP) which alleviates the level of transmission congestion during the planning horizon. Due to the combinatorial nature of the proposed TEP model, a Benders decomposition approach intertwined with a manipulated disjunctive model is applied to decompose the original TEP problem into a master problem and two sub-problems standing for...
The issue of grid companies on how to appropriately allocate the limited funds among different grid construction projects in market environment is discussed. Based on the research on investment optimization for grid construction projects with the Analytic Hierarchy Process (AHP) based design concept, the index system for evaluating grid investment projects was constructed. Based on the AHP, the comprehensive...
Evaluation of the transmission investment project plays a great role in the grids construct. Taking account the factors of technology and economic, this paper put forwards a index system of transmission investment evaluation. Above all, matter-element analysis theory is introduced into the project estimation, and extension set is built, the ternary-matter-element model on object, character and eigenvalue...
Operation of grid enterprise has the following specialties, large investment, long operating circle, limited price of supplying electricity and higher requirement to security. Under these limited conditions how to improve technical economic value of grid investment and get reasonable returns must evaluate investment benefit according to scientific evaluation method. The article probes mathematics...
The key links in transmission network should be solved imminently with insufficient funds for construction. The power grid vulnerability assessment based on electrical dissecting method of electric power network gives electrical characteristics information of vulnerable links that should be typically strengthen for transmission expansion planning. In this paper, the methodology for odering the construction...
As a kind of new financing way, it is necessary to carry on comprehensive appraisal to the earlier stage investment feasibility of power grid financial lease. This paper set up the comprehensive evaluation index system of project feasibility from the investment environment, the credit of renter, financial affairs of the project The classical and limited matter-elements of the investment feasibility...
