Transmission planning in restructured electric power systems

2005 IEEE Russia Power Tech, 2005
Transmission planning in a restructured electric power system involves complex interplay between economics and engineering. To bridge the gap between economic and engineering considerations, this paper suggests a framework to clarify the interactions among various economic and engineering issues by reviewing recent theoretical and practical progress in

Reactive power planning for transmission grids with wind power penetration

IEEE PES Innovative Smart Grid Technologies, 2012
This paper proposes an application of Differential Evolution algorithm to power system reactive power planning with wind farms integration. The SVC device is used to minimize the real power losses and to improve the voltage profile during various operation scenarios disturbed by wind power variations.

Optimal transmission expansion planning for electric power systems

Electric Power Systems Research, 1985
Abstract This paper presents a new method for transmission expansion planning in which the utility loss revenue and the customer outage cost resulting from service outages are incorporated. A new algorithm based on the total probability formula is developed for evaluating the expected value of demand not served (EDNS) and the expected value of energy

Regional transmission planning for large-scale wind power

2009 IEEE Power & Energy Society General Meeting, 2009
To incorporate large-scale wind generation in the Midwest ISO footprint, bulk transmission planning is necessary. In this paper, transmission planning for large-scale wind power is explained in detail. In expansion planning, the wind generation capacities are estimated from state Renewable Portfolio Standards (RPS) and the wind generator locations are ...

Transmission planning considering spatial correlation of wind power

2016 IEEE PES 13th International Conference on Transmission & Distribution Construction, Operation & Live-Line Maintenance (ESMO), 2016
Due to similar meteorological conditions, neighboring wind farm outputs are correlated, which usually results in amplified uncertainty. However, wind power is assumed to be independent in traditional transmission planning, causing potential risks in wind integration and power system security.

Genetic algorithm-based power transmission expansion planning

ICECS 2000. 7th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.00EX445), 2002
Large-scale combinatorial problems such as the network expansion problem present an amazingly high number of alternative configurations with practically the same investment, but with substantially different structures (configurations obtained with different sets of circuit/transformer additions). This paper presents a development of a genetic algorithm

Transmission Network Expansion Planning for Iran's Power System

2006 IEEE International Power and Energy Conference, 2006
A long range transmission network expansion planning (TNEP) for Iran's power system as a developing country is accomplished in this paper. This study is accomplished with energy flow optimizing model (EFOM). One of the challenges for power industry restructuring is to maintain transmission system reliability.
