of genelink per hour (24 points a day). The detailed variables and related
boundary constraints can be listed as follows:

Generator The state variables of generators are as follows:

• P gni : Electrical power output (24 points a day)

• δ gi ∈{ 0 , 1 } : Startup/shutdown status, where, P gnmin ≤ F gni ≤ F gnmax

( i =0 ,..., 23 ,n =1 ,...,N g ),

• N g : Number of generator,

• P gnmax : Maximum output,

• P gnmin : Minimum output.

Genelink Genelink is a kind of absorption refrigerators, which can

decrease adding fuels by inputting wasted heat energy of generator. The
state variables of genelink are as follows:

• Q ggLni : Heat input values (24 points a day)

• Q cgLni : Output heat values (24 points a day)

• δ gli ∈{ : Startup/shutdown status, where, ( i =0 ,..., 23, n =

1 ,...,N gl , ) , ( i =0 ,..., 23, n =1 ,...,N gl , ),

0 , 1 }

• N gl : Number of genelink,

• Q ggLnimax : Maximum heat input values determined by output heat

values,

• Q cdi : Air-conditioning load,

• Q rcgLn : Rated air-conditioning output.

Heat Exchanger The state variables of heat exchanger for heating/hot

water supply are as follows:

• Heat Exchanger for Heating Q ghni : Heat energy input values (24

points a day) δ hexhi ∈{ 0 , 1 } : Startup/shutdown status, where 0 ≤

A hexhn Q ghni ≤

Q hdi ,( i =0 ,..., 23 ,n =1 ,...,N hexh ), N hexh :Number
of heat exchanger for heating, Q hdi : Heat load, A hexhn :Coe cientsof
facility characteristics.

• Heat Exchanger for Hot Water Supply Q gwi : Heat energy input values

(24 points a day) δ hexwi ∈{

0 , 1 } : Startup/shutdown status, where,

0 ≤ A hexwn Q gwni ≤ Q wdi , ( i =0 ,..., 23 ,n =1 ,...,N hexw ), N hexw :

Number of heat exchanger for hot water supply, Q wdi : Hot water supply
load, A hexwn : Coecients of facility characteristics.
