Design of Grid Model Parameter Test System for New Energy Power Station

With the increasing proportion of photovoltaic and wind power generation installed capacity, when large-scale access to the power grid system, due to the inherent unstable factors of photovoltaic and wind power generation, if they are not strictly connected to the grid model parameter test, there will be great security risks to the safety of power grid operation. This paper mainly focuses on 10 kV/35 kV new energy power stations. A design method for testing model parameters of photovoltaic and wind power stations with multiple voltage levels (10 kV/35 kV) is proposed, and practical demonstration is carried out through field test to support the grid connection detection of new energy.
