Abstract

In order to scientifically evaluate the economics of micro-grid planning scheme

the economic comprehensive evaluation of micro-grid mathematical model is put forward based on the ideal vector space projection theory. A comprehensive evaluation index system applicable to the characteristics of the micro-network planning is built up

which includes initial investment cost

operation and maintenance costs

energy efficiency

environmental benefits

reliability efficiency

effectiveness of government subsidies

loss reduction benefits

and delay the grid investment benefit

etc. On this basis

the optimization of micro-grid planning scheme is achieved with the ideal vector space model and gray vector projection principle. Through calculation and analysis of micro-grid demonstration project on an actual

the validity and superiority of the model is verified. The results show that the model can take into account of the key index which may influence the micro-grid planning scheme and can quantize the advantages and disadvantages of micro-grid planning scheme

and guide the investment for micro-grid planning.
