document: Successive expansion method of network planning applying symbolic analysis method The conventional power system network successive expansion planning method is discussed in the context of the new paradigm of competitive electric power , energy and service market . In sequel , the paper presents an application of the conceptually new computer program , based on the symbolic analysis of load flows in power system networks . The network parameters and variables are defined as symbols . The symbolic analyzer , which models analytically the power system DC load flows , enables the sensitivity analysis of the power system to parameter and variable variations -LRB- costs , transfers , injections -RRB- , a valuable tool for the expansion planning analysis . That virtue could not be found within the conventional approach , relying on compensation methods , precalculated distribution factors , and so on . This novel application sheds some light on the traditional power system network expansion planning method , as well as on its possible application within the system network expansion planning in the new environment assuming the competitive electric power market
