Table 6.1 Factors power projects put into operation the border-sensitive analysis table
Region / type of load level bl] l total electricity bl2]
Of which:
) l form points out the direction for the regional classification type power supply included; the border for each direction of factors,including:
Load level of peak demand,the total areas of electricity,the main exchange line capacity,etc.;
2) forms the contents of the three cases for the optimization of capacity:for example,x [,y habits,their specific meaning for x
He borders being equal,only the factors corresponding to lower some standards (such as to reduce the load level of electricity
Total ......) corresponding to the type of the corresponding region of the installed capacity of generating units,y is the installed capacity under normal circumstances,
z to the boundary element standards to improve the optimization of a certain capacity.
This table clearly reflects:(a) from the column direction,in which case changes in the
Various types of regional changes in installed capacity of power optimization; (b) from the direction of view,the priority areas of various types of power
Of installed capacity by the change and what factors affect the rate.
The installed capacity of the border in accordance with the sensitive analysis of factors that form the basis of installed capacity of available tables,in particular:
Form the basis of installed capacity of 6.2 Table

6.2.2 Fine competitive power project evaluation
In the previous section,the status of the system,the future load demand and the transmission network expansion program,taking into account
Border factors,all power will be voted into power,and the inferior border power supply three categories,
The following types of power projects on the major competitiveness of fine judge further defined the region from various types of electric
The status of the source,in order to provide a sufficient basis for planning and decision-making.Competition in the electricity market,the direct operating costs of power generation
Then the impact of power generation company's pricing,revenues and market share,the paper will be the cost of generating the level of operation
Indicators as a fine judge.
Operating costs including power generation in two parts:() l variable operating costs,mainly fuel costs; (2)
Fixed operating costs,mainly for equipment depreciation.
Comparison of intuitive part of variable costs,fixed operating costs,however as a result of various types of power do not stand-alone capacity
The same factors that make does not have direct comparability,for which needs to be converted into units of energy equipment depreciation,
That is:() l calculation of total investment,including the power plant,unit,desulfurization equipment,access costs,etc.; (2) Calculation of deduction
In addition to calculating the residual value at the end of the value of an effective investment.Based projects for the P,the investment payback period for the T,use
= T1-years period for the purpose of calculating the investment projects that have occurred in the number of years,will be converted to invest for the future P in T
The level of the total electricity load-based
