abstract
The present invention relates to a kind of active distribution network net capability computational methods based on second order cone relaxation, belong to electric power system optimization evaluation areas.The method of the present invention includesConsider the scene of all different main transformer failures, introduce the parameter for being used newly in indicating different faults scene, establish an active distribution network net capability computation model to relax based on second order cone, its object function needs the second order cone constraint of trend variable relation described in the every technological constraint for meeting operation of power networks and the setting active distribution network to maximize the network power losses after institute's on-load amount total in active distribution network subtracts weighting.Each node load value accordingly when by the solution of the model, the net capability assessment result of the active distribution network can be obtained, that is, meet lower of 1 restraint conditions of the distribution transforming N band total load upper limit, and taking upper load limit.The assessment models that the method for the present invention is established are very fine, tally with the actual situation, and be easy to solve, and have very strong practicability.
