Analysis on the allowed output of distribution generation considering distribution network static security

Position and capacity of the distributed generations (DG) have a direct impact on static security of the distribution network. A method to calculating maximum allowed output of DG for each node using voltage sensitivity and current sensitivity based on linearized power equations is proposed, and it reduces the computation obviously. The calculation results are analysised. The method of installing DSTATCOM to improve maximum allowed power of DG is analysised. The accuracy and effectiveness of this method is tested by IEEE-33 system.
