This paper investigates the limitations of static hosting capacity (SHC) in accommodating distributed generation (DG) in electricity networks. It assesses dynamic hosting capacity (DHC) as a more flexible alternative derived from hourly network operation and considers DG output and demand variability. Furthermore, network assets' N-1 contingencies and their probabilities are considered, leading to the definition of the security-aware DHC (SDHC). A case study reveals SHC's limitations due to deterministic N-1 criteria. DHC increases annual injectable energy by 56% to 69% compared to SHC. Variations between DHC and SDHC are below 0.01% due to low N-1 probabilities. This finding points out the potential of dynamic hosting capacity definitions, allowing more efficient use of the existing network and facilitating the integration of new DG capacity with reduced connection costs and time.
