摘要
With the promotion of transmission price policy, power loss has drawn increasing attention in the planning and operation of the power system. This paper proposes the power loss-oriented transmission network expansion planning (TNEP) considering pyramidal approximation (PA) power flow and N-1 contingency. The objective of the proposed method is selected as the sum of the power loss cost and the line construction cost. The pyramid approximation is used to linearize the branch flow model for tractable calculation of the power loss. N-1 contingencies are considered to guarantee the security of the planning results. Case studies in the Garver 6-bus test system validate the economic improvement and operational security under the proposed method.
