In this paper, a new methodology to assist system planners is proposed, which is able of providing a set of good solutions to the addition of new transmission lines, in order to reinforce the sub-transmission network. To circumvent the combinatorial explosion of reinforcement alternatives, a constructive heuristic algorithm is used for adding new branches to the sub-transmission grid. Based on performance...
Frequent occurrences of meteorological disasters (MD) in recent years have revealed the deficiencies of traditional transmission network planning (TNP) methods, which fail to establish mathematical relationship between the MD and the transmission line outage rate (TLOR) when calculating the vulnerability index of transmission network. As a result, the planning schemes are usually unable to determine...
This paper presents an algorithm for the microgrid planning as an alternative to the co-optimization of generation and transmission expansion planning in electric power systems. The integration of microgrids in distribution systems will offer a decentralized control of local resources for satisfying the network reliability and the power quality required by local loads. The objective in this paper...
Transmission network was recognized as natural monopoly and almost everywhere subject to some kind of regulation in a restructured electricity market. The role of the transmission system is to provide an indiscriminate access for all market players along with an acceptable level of reliability and security. Regulating authorities have to decide about the augmentation investment. As an on going research...
This paper proposes a mixed-integer stochastic programming approach to the solution of generation and transmission line expansion planning problem including consideration of system reliability. Favorable system reliability and cost trade off is achieved by the optimal solution. The problem is formulated as a two-stage recourse model where random uncertainties in area generation, transmission lines,...
