LONG-term dynamic modeling of renewable energy sources

摘要

Behavior of grids with different types of sources should be investigated during variable conditions like daily demand change, sunshine and wind fluctuations. Dynamic model is used for simulation of parallel operation of different types of dispersed sources — wind farms, photovoltaic plants, small hydro and gas turbines. The first two sources are modeled according up to data knowledge ([1] and [2]). Paper pays attention to appropriate load/frequency and reactive power/voltage regulation of all source, not only bulk power plant, but embedded small and renewable sources as well.
