State Grid Qihe Power Suply rolls out digital DC microgrid in Shandong Province

This is the first village-level of its kind launched in the province.

State Grid Qihe Power Supply Company developed the first village-level digital direct current (DC) microgrid in Shandong Province in China.

In a statement, the grid said the original distribution grid is turned into a 750-volt DC distribution grid by integrating four types of typical electric usage scenarios.

These are distributed photovoltaic, energy storage, vehicle grid interactive charging piles and DC loads.

“The construction of the first village-level digital DC microgrid in Shandong Provence has solved the problems of uneven electric equipment load and high electricity consumption fluctuations in areas with high access rates of distributed photovoltaic projects,” the company said.
