Power Flow Calculation for Distribution System Including PV Type Distributed Generation

摘要

After distribution network with PV type distributed generation, it emerged PV nodes. Advanced forward and backward substitution method is proposed based on ant colony optimization method to improve power flow solution, which is a method based on ant colony optimization calculation algorithm of reactive power correction, improved the model of PV type distributed generation in the power flow calculation. Use PSSSINCAL power system simulation software to set up the model of distribution System including PV type distributed generation. Through the results of simulation calculation show that the algorithm can cope with power flow solution for distribution system including PV type distributed generation effectively, and the convergence property is very good.
