Applicability of wind solar and DC microgrids

DC Microgrid for Wind and Solar Power Integration Abstract:Operational controls are designed to support the integration of wind and solar power within microgrids. An aggregated model of renewable wind and solar power generation forecast is proposed to support the quantification of the operational reserve for day-ahead and real-time scheduling.

DC microgrids power supply reliability can be enhanced by optimizing control of wind and solar PV power units and making use of inertia to minimize the impact of rapid changes in wind speed and solar irradiation on bus voltage.

DC microgrids are mostly composed of solar PV panels and wind turbines, as well as energy storage devices like supercapacitors and batteries. This integration guarantees a steady supply of power while simultaneously utilizing renewable energy from the sun and wind.

Solar energy is an important part of a DC microgrid, with the main goals to save energy costs and reduce dependency on the AC power grid. A dedicated power converter conditions the variable voltage from the solar panels to a stable DC link voltage.

Due to the high number of power electronic converters, renewable integrated DC microgrids are more prone to instability than utility grids or synchronous generators, . The power electronic converters used to link solar PV and wind can be controlled in a variety of ways, each of which can improve voltage stability.

Uncertainty modeling approaches Uncertainties in wind and solar energy generation in DC microgrids can be handled with different approaches like time series approach, ensemble forecasting, stochastic models, probabilistic graphical models, machine learning algorithms, Markov models, extreme value theory, and Monte Carlo.
