Power supply technology and economic analysis of green industrial park
Industrial parks play an important role in promoting economic development.Within them,the production activities require huge amount of energy and thus a reliable and cost-effective power supply technology is needed to guarantee the operation of energy-intensive industries.This paper analyzes the system structures and operation characteristics of the current main power supply modes,including self-contained power plant,power grid purchasing,isolated island microgrid and grid-connected microgrid.The evaluation index system of power supply technology is built based on cost-effectiveness,reliability and environmental benefits.Finally,taking an electrolytic aluminum production park as an example,this paper analyzes the cost-effectiveness of the above four power supply modes in industrial parks.And the sensitivity analysis of future carbon price and energy storage cost is also conducted.Our results may provide some references for industrial park investors and relevant policy makers.
