Wherein, NF is capital project annual cost, and Z is scheme gross investment, and U is scheme annual operating cost, and r0 is power industry investment
The rate of recovery, n are industrial economy service life, and R is to lack power generation loss in economic index year；
Second optimal case output unit, for obtaining the smallest side of capital project annual cost in each initial option access scheme
Case is exported as optimal marine wind electric field access scheme.
