Optimization Assessment of Grid-tied Wind and Solar Hybrid Power System for Industrial Factory in Vietnam

Abstract

Currently, the transition from fossil energy to renewable energy is considered an inevitable trend to reduce greenhouse gas emissions, protect the environment and minimize dependence on fossil fuels. In Vietnam, the use of renewable energy in production and business activities for sustainable development is also increasingly interested by businesses. Installation of solar power systems and wind power systems can help companies and industrial plants directly use electricity generated by clean power sources to save electricity costs and move towards friendly solutions with the environment. In this paper, optimization study results for a typical non-fired brick factory in Quang Binh province, Vietnam show that the grid-tied wind and solar hybrid power systems in scenario 1 are considered to achieve more environmental, economic, and technical efficiency than grid-tied solar power systems in scenario 2. The optimal grid-tied hybrid power system configuration includes wind power with the capacity of 300 kW and solar power with the capacity of 1,500 kW, this system has a net present cost (NPC) of US$ 5,596,978, the cost of energy (COE) of US$ 0.0847/kWh, the investment cost of US$ 1,140,000, and operating cost of US$ 384,877.
