New Energy and UHVDC Power Absorption Capacity Analysis Method Based on Refined Operation Simulation Technology

Abstract In order to comprehensively consider a variety of complex factors such as new energy integration, maximum and minimum load, network security constraints, and analyse the new energy absorption capacity of the power grid before and after the UHVDC power access in the province, and study the steady-state power absorption capacity of UHVDC, this paper deeply studies refined time series operation simulation model, designs constraints before and after the UHVDC power access, and establishes a new energy and UHVDC power absorption capacity analysis method based on refined operation simulation technology, and applies this method to analyse the power grid of the province before and after the UHVDC power is put into operation. This method provides technical support for demonstrating power supply and power grid planning schemes.
