Optimal Energy Management of Combined Cooling, Heat and Power in Different Demand Type Buildings Considering Seasonal Demand Variations

Abstract

According to energy information administration (EIA), 48% of the energy used in buildings is for heating and cooling purposes [5]. [...]charging of thermal energy to the storage tank by the large CHP and discharging of thermal energy by ADC from the storage tank will not involve energy-trading cost, i.e., free of cost: Thermal Storage Tank Constraints It can be observed from Equations (30)–(34) that the charging, discharging, and HCS calculations at each time interval t require the HCS information of previous time interval, i.e., time interval t − 1. [...]the value of HCS(t−1) at the first interval will be replaced with the initial value of thermal energy in thermal storage tank, i.e., SQTSTINI . Large CHP being the part of EEN, is not able to sell the heat energy directly to EEN. [...]electricity generated by large CHP is controlled by market price signals. 4.
