“…• Power supply reliability (C22) [37]: where ∆W E,T , ∆W H,T , and ∆W C,T represent the deviation of electric supply, heat supply, and cool supply at the T period, respectively; P L,E (t), P L,H (t), and P L,C (t) indicate the demand of users for electric load, heat load, and cooling load at the T period, respectively; P o,i (t) is the actual output power for i renewable energy units at the T period; P E,C (t) is the electric refrigerating at the T period; P CCHP,E (t), P CCHP,H (t), and P CCHP,C (t) are the actual power output of CCHP with electricity, heat, and cold at the T period, respectively; and P S,k (t) is the discharge power of k energy storage device at the T period. Any reader interested in the energy demand prediction aspect of an HES can refer to [38][39][40].…”
