Transmission network expansion planning is a very complex and computationally demanding problem due to the discrete nature of the optimization variables. This complexity has increased even more in a restructured deregulated environment. In this regard, there is a need for development of more rigorous optimization techniques. This paper presents a comparative analysis of three metaheuristic algo...

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 nodal analysis. In this way, the allocations are not determined and subequent studies are required to find the exact locations which as decomposed from the earli...

Nowadays, the transition from a conventional generation system to a renewable generation system is one of the most difficult challenges for system operators and companies. There are several reasons: the long-standing impact of investment decisions, the proper integration of renewable sources into the system, the present and future uncertainties, and the convenience to consider an integrated yea...

The increasing integration of renewable energies into the grid is calling for expansion power transport capacities in distribution system. Yet, could require long authorization procedures and cannot be always asserted. Therefore, a higher utilization existing becoming increasingly necessary today. This paper proposes new time series-based planning method systems using classical instruments as w...

Forecasting the future electric demand and its geographical distribution is a prerequisite to generate expansion-planning scenarios. The load growth pattern is related with the urban structure and its land-use. The model for simulating urban structures must be explicitly dynamic and must contains mechanisms for linking its macrostructure to micro behaviours. The paper presents a methodology, wh...

in this paper, first, a new criterion, titled “surplus percent of the customers” is defined for static transmission expansion planning in restructured power systems. then by a simple example, the new criterion is compared with some already presented market-based criteria and it is shown that the new criterion can realistically evaluate the transmission network expansion from the market view. in...
