Based on the characteristics of cooling

heating

electric

mechanical loads

and illumination in the smart grid area

the best optimization value is put forward by making use of the fundamentals of the pinch algorithm while considering the properties of electric power itself. When heat-exchange network is analyzed

kW is used as the unit of measurement in equations of all kinds of energy to promote graded use of multi-energy. A multi-energy optimization analysis method based on the improved pinch algorithm is proposed

with which both the lowest value of theoretic energy consumption and improvement ideas of multiple energy utilization can be achieved. What’s more

this method can be applied in many kinds of user in smart grid area

such as industry

public institution

data center and so on. This work is supported by State Grid Corporation of China (No. SGTJ0000KXJS140087).
