Research on Reactive Power and Voltage Characteristics Analysis and Reactive Power Configuration Strategy of Active Distribution Network

The access of the distributed power supply completely changes the structure and operating state of the distribution network, transforming the distribution network from a single-ended power supply structure and unidirectional power flow mode to multi-terminal power supply structure and a frequently changing bidirectional power flow mode. The high proportion of renewable distributed power distribution is distributed to the distribution network, and its output randomness superimposes the load volatility, which brings great difficulties to the optimization control and the operation situation prediction analysis, so that the potential of multi-type reactive power equipment can be fully explored, from Source-network-load-storage multi-dimensional broadening of reactive power optimization control "feasible domain" becomes necessary.
