Integrating more renewable energy sources into the grid leads to a vulnerable power system and presents challenges for planners. This paper proposes probabilistic overload constraint based AC transmission expansion planning model. In terms of economic dispatch, generation adequacy network constraints are assessed using participation factor flow. Generation factors, which handled in flow equatio...

The restructuring of global power industries has introduced a number of challenges, such as conflicting planning objectives and increasing uncertainties, to transmission network planners. During the recent past, a number of distributed generation technologies also reached a stage allowing large scale implementation, which will profoundly influence the power industry, as well as the practice of ...

Transmission network expansion planning (TNEP) is a basic part of power system planning that determines where, when and how many new transmission lines should be added to the network. Up till now, various methods have been presented to solve the static transmission network expansion planning (STNEP) problem. But in all of these methods, transmission expansion planning considering network adequa...

This paper describes an implementation of Tabu Search to cope with long-term transmission network expansion planning problems. Tabu Search is a metaheuristic proposed in 1989 to be applied to combinatorial problems. To assess the potential of our approach we will test it with two cases of transmission network expansion planning. The results obtained by our approach let us to conclude that TS is...

The paper presents a modeling framework to analyze some important issues associated with operation planning of a power system. Major activities involved in operations planning of large integrated power systems are considered simultaneously to ensure optimal utilization of generation and transmission capacity. The model also examines optimal transmission expansion plans vis-aÁ -vis fuel supply i...

The transmission expansion planning problem in modern power systems is a large-scale, mixed-integer, non-linear and non-convex problem. This paper presents a novel mathematical model to solve security constraints transmission system expansion planning problem via a constructive heuristic algorithm (CHA). The basic idea comes from Garver’s work applied to the transportation model; nevertheless t...

Since the development of methods to quantify transparent exopolymer particles (TEP) 1993, it has been shown that these gel-particles are not only ubiquitous and abundant, but also play a significant role in the biogeochemical cycling of elements and the structuring of food webs. TEP may be quantified either microscopically or colorimetrically. Although data based on measurements using one or ot...

Generation Expansion Planning (GEP) is one of major modules of power system planning studies, normally performed for the nex 10-30 years horizon. The current industrial practices are to find the generation requirements based on a&#10&#10nodal analysis. In this way, the allocations are not determined and subequent studies are required to find the exact locations &#10 which as decomposed from the...
