Solar PhotoVoltaics (PV) integration into the electricity grids significantly increases complexity of Transmission Expansion Planning (TEP) because solar PV power generation is uncertain and difficult to predict. Therefore, this paper proposes optimal planning method for transmission expansion combined with generation. The problem solved by using Long Short-Term Memory (LSTM) forecasting radiat...

A novel integrated optimization method is proposed to combine both generation and transmission line expansion problem considering bus voltage limit. Most of the existing researches on the combined generation and transmission expansion planning cannot consider bus voltages and reactive power flow limits because they are mostly based on the DC power flow model. In this paper the AC power flow mod...

In terms of the transmission network development case selection, there are deferent emphases for the development department, power dispatching and other departments, and evaluation indexes and methods in case selection of transmission network development are deferent to take, as a result it is difficult for the developing, scheduling and other departments of grid to form an objective, comprehen...

There is an intense debate regarding the best way to attract investment for the long-term expansion of an electricity transmission network. We study three hypotheses: the long-term financialtransmission-right hypothesis; the incentive-regulation hypothesis; and the market-power hypothesis. The first approach derives optimal transmission expansion through auctions of longterm financial transmiss...

This paper presents a comprehensive study on monoand multi-objective approaches for electrical distribution network design using particle swarmoptimization (PSO). Specifically, two distribution network design problems, i.e., static and expansion planning, are solved using PSO. The network planning involves optimization of both network topology and branch conductor sizes. Both the planning probl...

Traditional methods of evaluating transmission expansions focus on the social impact of the investments based on the current generation stock which may include firm generation expansion plans. In this paper, we evaluate the social welfare implications of transmission investments based on equilibriummodels characterizing the competitive interaction among generation firms whose decisions in gener...
