Research on wind and solar penetration in a 9-bus network

Variability and uncertainty are the inherent characteristics of the power system. Many countries´ national laboratories have studied wind and solar penetration to achieve large percentage generation capacity to reduce carbon emission and air pollution. There could be a stability problem when many wind turbines and PV farms integrated into power grid. The penetration level of a power system is closely linked with how much flexible generation capacities installation in the network. To deal with intermittence of wind and solar energy generation, these generators must have the capability of fast response. Various scenarios will be investigated to demonstrate the potential in maximizing the use of variable renewables. Naturally, for a full scale project to be established, it is also required to carry out a cost-benefit analysis. But in terms of technology, it shows that there are many challenges and our fellow engineers will have a huge opportunity to make contributions.
