Wanshan Island Microgrid won the bid

How can microgrids help Yongxing Island?

Microgrids are an important solution to tackle the energy challenges of islands. Yongxing Island has a tropical monsoon climate with long annual sunshine hours and is surrounded by a vast sea area, making it suitable for utilizing solar, wind, and wave energy power generation technologies.

Are island microgrids a viable solution?

Island microgrid (IM) systems offer a promising solution; however, optimal planning considering diverse components and alternatives remains challenging. Using China's Yongxing Island as a case study, we propose a novel indicator system integrating economic, resilience, energy, and environmental dimensions.

How much does Yongxing Island microgrid cost?

Based on NPC, Fig. 6 shows the detailed cost summary by components and cost types of the identified optimal scheme of the microgrid of Yongxing Island. The costs from capital, replacement, O&M, fuel, are salvage are 89.34, 21.35, −29.26, 34.80, and −14.85 Million CNY.

How much hydrogen is produced in Yongxing Island microgrid system?

The hydrogen load in the Yongxing Island microgrid system is met by both the reformer and electrolyzer, which account for respectively, 58.20% and 41.80% of total hydrogen production. In this configuration, the levelized cost of hydrogen is 51.83 CNY/kg for the island. Fig. 9. Monthly thermal (a) and hydrogen (b) production.

What is the difference between islanded and grid-connected optimal operation?

Islanded optimal operation mainly considers for stability and ability of continuous operation. While grid-connected optimal operation mainly focuses on improving economic indicators of MMGs and clean energy utilization ratio.
