Transmission expansion planning for wind turbine integrated power systems considering contingencies

Abstract

Increasing penetration level of wind turbines in power systems reveal new challenges for the power system planners. Transmission expansion planning is one of the most important planning problems to maintain secure and reliable operation of power systems. In this study, a new transmission expansion planning methodology considering N-1 contingency conditions is proposed to find the location of new transmission lines while minimizing investment cost and curtailed wind energy. To deal with the uncertainty of load and output power of wind turbines, fuzzy clustering based probabilistic method is used for determination of load and wind scenarios. Proposed methodology uses the DC-power flow equations based optimal power flow and integer genetic algorithm to determine the locations of new assets and it is applied to the modified IEEE 24-bus test system.

Reliability-constrained dynamic transmission expansion planning considering wind power generation

“…In particular, the two coal plants of 152 MW placed at bus 1 are replaced by 524 wind turbines of 2 MW each one, whereas the 130 MW coal plant at bus 15 is replaced by 396 wind turbines also having capacity of 2 MW. The replacement of conventional generation to renewable energy sources is a common practice in the literature [22,27]. At the end of the planning horizon, the modified system presents in total: 9294 MW of thermal power capacity; 2760 MW of wind power capacity; and 8500 MW of peak load.…”

“…Also, it does not consider the wind curtailment uncertainty. In [22], a methodology is proposed to minimize the investment cost, reducing the wind curtailment under several wind availability and contingency scenarios; however, only single contingencies are evaluated. Similarly, a robust approach is proposed in [23] to minimize the cost associated with the wind curtailment in the worst case of the N-1 criterion.…”

An auction framework to integrate dynamic transmission expansion planning and pay-as-bid wind connection auctions

“…Initially, much of this literature has considered wind investment decisions in a centrally-planned framework (e.g. Hemmati et al, 2016;Ugranli and Karatepe, 2014), where…”

Time‐horizons in the planning and operation of transmission networks: an overview

“…In addition to the various tools and methods, there is an immense requirement of tools and knowledge-based schemes for decision making to integrate RES under market regulations and uncertainties [79,80]. This is a challenging task because of stochastic behaviour, non-linearities, and non-convexities [62]o f RES.…”
