Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] An embodiment of the present invention provides a symmetrical method for obtaining power loss sensitivity of an AC / DC hybrid power grid, which includes the following steps:
[0016] According to the known power flow solution of the AC-DC hybrid power grid, the independent vectors of the AC-DC hybrid power grid are obtained;
[0017] The sensitivity of the node voltage vector to the node injection power vector is obtained according to the relationship equation between the independent vector, the node voltage vector and the independent vector, and the relationship equation between the node inj...
