Renewable energy generation systems have been developing rapidly in recent
years. However, renewable energy systems have the problem of large power
abandonment. In this paper, two different hybrid renewable energy systems
(HRESs) have been designed for satisfying the electrical demand of a large office
building in Changchun. A comparative analysis between two strategies is also
presented to find out the best capacity for the proposed HRESs. The first HRES
consists of solar PV, wind turbine, battery storage system (PV-WT-BATT) and
load demand of 5,000 kWh/d. The second consists of solar PV, wind turbine,
battery storage system, electrolyzer, hydrogen tank (PV-WT-BATT-EL-HT) and
load demand of 5,000 kWh/d. The two HRESs are optimized for Net Present
Cost (NPC), Levelized Cost of Energy (COE), Operating Cost and the rate of
excess electricity minimization. The techno-economic analysis of the two HRESs
is conducted using the HOMER Pro software platform. This study provides a
complete guideline for determining the optimum component capacity to ensure
costing estimation for the optimized performance of the two HRESs. |
