On the eve of the Spring Festival, the reporter visited an island observation station - a microgrid settlement in the small island camp. The sky was blue and the clouds were white, and the waves rolled over. On the eve of the Spring Festival, when the reporter came to an island observation station for an interview, the officers and soldiers were conducting equipment maintenance and repair. "Since the outpost was connected to the 'power grid', the operation of equipment on the island has become safer and more reliable, and everyone's combat readiness training and learning life have been more guaranteed," stationmaster Wang Lun told reporters. The "power grid" referred to by Wang Lun is actually an off grid intelligent microgrid system that integrates functions such as diesel engine power generation, photovoltaic power generation, wave energy generation, and energy storage. This system is one of the first national energy demonstration projects coordinated by the Logistics Support Department of the Central Military Commission and the National Energy Administration. "In the past, we relied on diesel engines for power generation, which not only caused loud noise and heavy pollution, but also increased the burden of security by regularly transporting oil to the island." Wang Lun explained to reporters the changes brought about by the "power grid" on the island. "In the past, the voltage was unstable and there were power outages every three days or two. Now that the" power grid "is connected, there is almost no power outage, and the equipment failure rate has also significantly decreased..." The weather on the "power grid" on the island is new. ". The reporter saw on the island that many buildings in the camp were equipped with solar panels on the top floor; Wave power generation equipment has been put into use on the sea surface several kilometers away. The reporter walked into an energy storage equipment factory and technician Huang Shengkun, who was repairing the equipment, said, "The new generation of clean energy helps with power supply, reduces the burden on the military, saves fuel, and reduces carbon emissions!" The reporter saw in the greenhouse of the camp that green yellow melon seedlings began to climb vines, and newly planted rapeseed seedlings sprouted green shoots. "With a stable and reliable power supply, a variety of vegetables in the greenhouse are growing well. The 'power grid' has made our lives more secure," Su Zile, the head of the supply station, said to the reporter with a smile while taking care of the seedlings
