Coordinated generation and transmission expansion planning in deregulated electricity market considering wind farms

Abstract

a b s t r a c tThis paper deals with a coordinated generation expansion planning (GEP)etransmission expansion planning (TEP) in competitive electricity market. In the proposed method, GEP and TEP are performed at the same time, with consideration of wind farm uncertainty. The uncertainty is modeled by normal probability distribution function (PDF) and Monte-Carlo simulation (MCS) is used to include the uncertainty into the problem. The planning is managed for two master and slave levels. At slave level, all generation company (GENCO) and transmission company (TRANSCO) maximize their profit and then at master level, the system constraints are checked by independent system operator (ISO). In other words, the proposed planning aims at maximizing the expected profit of all GENCOs and TRANSCOs, while considering security and reliability constraints such as reserve margin and loss of load expectation (LOLE). The proposed problem is a constrained, nonlinear, mixed-integer optimization programming and solved by using particle swarm optimization (PSO) method. Simulation results verify the effectiveness and validity of the proposed planning for maximizing GENCOs and TRANSCOs profit in the presence of wind farm uncertainty under electricity market.

An Extreme Scenario Method for Robust Transmission Expansion Planning with Wind Power Uncertainty

“…It should also be noted that, although the constraints in (16) are in the form of an equality, this can be transformed into an inequality constraint by the equality relaxation method. However, we do not discuss this in further detail here.…”

Advanced model for joint generation and transmission expansion planning including reactive power and security constraints of the network integrated with wind turbine

“…The first and second terms introduce the revenue of the generation unit and the transmission owners, respectively. Also, the costs of the generation unit and transmission owners are presented in the third and fourth terms, respectively . In this paper, the proposed model is solved from the investors' point of view.…”

“…Figure and Equation present the relationship between the wind speed and the output power of the wind unit. Moreover, the probability distribution function (PDF) of wind speed is expressed in , which follows the Weibull distribution . In this paper, stochastic programming, which is the common uncertainty management tool, is employed.…”

Multistage generation expansion planning incorporating large scale energy storage systems and environmental pollution

“…GEP has also been studied considering several objective functions such as minimizing planning cost [2,17], maximizing planning profit in deregulated electricity market [18], maximizing reliability [13], minimizing environmental pollution [19], and considering demand-side management programs [20]. As well, GEP has been investigated subject to various constraints such as reliability [3], environmental pollution [21], investment cost [22], and security [23].…”
