Protection and control of domestic PV based micro-grids

At its extreme level, the concept of distributed generation (DG) involves each household generating its energy from photovoltaic cells. This approach is particularly suitable in rural electrification projects. A meshed micro-grid is an attractive solution for energy generation and sharing in domestic electrification projects. However, protection and control in a meshed power network setup is a challenge. This is true because unlike in radial architecture power grids, a mesh introduces more interconnections and interfaces which need to be protected.
