Research Of Power Transmission Network Optimization In The Electricity Market Environment

Power transmission network planning is an important work of the electricity market research field. The paper analyzes the developments and new challenges of the network planning in the electricity market environment in details. The paper summarizes network planning models and proposes the network planning framework for the design under market conditions.Considering the requirement that conform to the load growth continuously and the problem of expansion gradually, the new model that balance the economic and the stable factors ensure the stability of network, avoiding the unnecessary cost in the quadratic expansion. It shows that the result is effective and accurate based the calculation and analysis.In the light of constrains in the multi-objective optimization problem in the network planning, we made an improved algorithm, which is proved to efficiency and feasible application in transmission network optimal planning.
