【Abstract】 The suitable allocation of the measuring set from the point of view. of minimizing estimation error is one of the fundamental problems in power system state estimation (PSSE) In this paper we have answered the following three questions.(1)"Where" should we add a measurement most effectively in order to decrease the estimation error. (2)"What kind" of measurement should be used.(3)"Which" measurement could be removed from a given measuring system which would produce the least effect upon the performance of PSSE.An algorithm for designing a new or improving an existing measuring set is developed. Computational comparison on IEEE 14 buses.test system with some other methods already proposed in literatures has been made, and better results are obtatined.The relation between, the estimation error and the numerical stability of estimation has reen discussed, and is included in the paper also更多还原
