Effect of electricity feed-in tariff on the planning of CCHP Micro-systems

Abstract

The electricity feed-in tariff has a profound influence on economic efficiency of a combined cooling heating and power (CCHP) micro-systems. In this paper, economic analysis of a CCHP micro-grid system is performed in different electricity feed-in tariff cases, based on a comprehensive CCHP micro-grid system framework and mathematical model considering energy storage equipment, electrical heating equipment and electrical cooling equipment. Then, the influences of electricity feed-in tariff on system design and capacity sizing of the equipment are studied.
