Capital budgeting process for electric power utilities—an analytic hierarchy process approach

Capacity planning for fossil fuel and renewable energy resources power plants

“…One of the reasons for selecting this method is provision of group cooperation. To mix different judgments of people, all the even comparisons matrixes were gathered and mixed the judgments by geometrical average and get relative weights of criteria and items [2].…”

“…We should form the even comparison matrix of items toward all criteria toward objective. In this case, economical and technical information table (2) and 3which is collected by Tavanir production planning office organization [3] is used and also considering senior manager and industry experts points of view related to power plant energy, industry and numerous seniority meetings and expertise executive panels and using hierarchical analysis method, special weights are specified according to their importance. Even comparisons of this paper are done during three phases and according views of some experts in this field.…”

“…The first limitation represents total capacity of selected projects should be among required predicted load according to 25 to 30 percent circulatory storage. Restriction (2) and 3states the highest point of technologies. 4 restriction shows non-negative capacity of power plants.…”

“…As throughout net load factor (LF) is estimated 62 percent [5] so limitation of produced energy of power plants are shown by limitation (7). Restriction (8) P pv + P Ge + P M + P Sh + P Solar ) (2) 0.62*( P W + P B + P Fc + P pv + P Ge + P M + P Sh + P Solar ) <= PF W * P W +PF B * P B +PF M * P M +PF Ge * P Ge +PF Sh * P Sh +PF Solar * P Solar +PF pv * P pv +PF Fc * P Fc (3) P W , P Ge , P M , P pv , P Sh , P Solar , P B , P Fc >= 0 (4) Now, by the gained total preference weights from firsts, second and third phases and tables (2) and 3data , problems of linear programming are as below and by its solution capacity of power plants foundation will be obtained.…”
