Now that renewable technologies like wind and solar are largely commoditized, investors and utilities are looking for ways to improve their margins, and they're turning to improved control systems to do it.
Renewable energy sources has recently been receiving more attention due to cost competitiveness and environmental sustainability. Due to the investment cost of renewable power generation systems, it is important to operate the systems near their maximum output power point, especially for wind and solar PV generation systems. In addition, since wind and solar PV power resources are intermittent, accurate prediction and modeling of wind speed and solar insolation are necessary. Furthermore, to have a more reliable power supply, renewable power generation systems are usually interconnected with the power grid.
