Monitoring and control of PV systems


The rapid increase in the penetration of RES is creating many problems to electric power systems, especially low-inertia, islanded grids 1. In periods of high PV penetration, the Cyprus system needs to curtail power generation from residential PV systems to ensure the security of the system and avoid congestion 2. This action leads to waste of renewable energy, loss of revenue for the residential customers, higher household electricity prices.

The main issues contributing to this problem are:

  • Lack of proper monitoring on residential PV systems: This leads to inaccurate PV generation estimations, higher uncertainty, and higher RES curtailments.
  • Lack of controllability in small PV installations: Inability of the system operators to control and disconnect PV systems at a lower granularity level.


In this project, you have to develop a low-cost residential PV monitoring and control system that will provide better data for forecasting and control and allow the system operators to disconnect and reconnect small PV systems.
