BUILDING HARDWARE MODEL FOR SOLAR POWER STATION CONNECTED GRID, APPLIED AT OFFICES, SCHOOLS, ENTERPRISES IN LAO CAI CITY

Abstract

Lao Cai, a northwest mountainous province, has great potential for tourism development and mineral exploitation for socio-economic development. As a province bordering China, every year Lao Cai still has to buy electricity from abroad. Therefore, to reduce the load for domestic fossil power sources is gradually depleting and less dependent on electricity purchased from China. The construction of solar power stations in Lao Cai in particular and in Vietnam in general is essential and in line with the Government's policy. Currently, the distribution and installation of solar power stations is very popular. However, in Vietnam, most inverter and grid-connected controllers are imported from abroad. This article presents research results to create a solar power system with Vietnamese brand. The hardware models are installed and tested in 3 different locations in Lao Cai city with a total capacity of up to 20 KW.
