The increasing consumption of electricity over time forces different countries to establishnew power plants and transmission lines. There are various crisp single-objective mathematicalmodels in the literature for the long-term power generation and transmission expansion planning tohelp the decision makers to make more reasonable decisions. But, in practice, most of the parametersassociated wit...

Power system restructuring has changed transmission expansion planning (TEP) and caused many complications due to conflicting contradictory objectives. The capacity would significantly affect the revenue of investor-owned renewable energy sources (RESs). Thus, investment decisions on merchant RESs must be considered in TEP studies conducted by operator (TSO). In this regard, paper aims propose ...

Multi-year generation and transmission expansion planning (MY-G&TEP) is a critical issue in power systems. The present paper considers the optimal placement of Fixed Series Compensation (FSC) Phase Shifting Transformer (PST) proposes pool-market-based mathematical model for maximizing social welfare (SW) reducing investment costs lines new plants. Following determination strategy, compares usef...

A new market based approach for transmission expansion planning in deregulated environments is presented in this paper. In this approach, transmission-planning decisions are made based on the electric power market conditions. The main contribution of this research is 1) Introducing a new probabilistic tool for analyzing the electric market conditions, 2) Defining new criteria for ranking transm...

this paper presents a framework for long term transmission expansion planning in competitive, electricity markets. transmission lines and phase shifters are taken into account as expansion options. maximization of the network users' benefits, with satisfying security constraints are considered as the criterion for transmission expansion planning. the elements of the objective function are the...

The secular increase of load causes the evolving power system to operate near critical margins. In such attitudes, probability cascading line outages, as major reason for recent blackouts, is much more than expected. As a result, an innovative approach optimal AC transmission expansion planning (TEP) minimize risk blackouts presented in this paper. proposed multi-objective AC-TEP problem minimi...

This paper presents a multi-objective transmission expansion planning (TEP) framework. Rather than using the conventional deterministic reliability criterion, a risk component based on the probabilistic reliability criterion is incorporated into the TEP objectives. This risk component can capture the stochastic nature of power systems, such as load and wind power output variations, component av...

Increasing the intermittent outputs of renewable energy sources (RESs) has forced planners to define a new concept named flexibility. In this regard, some short- and long-term solutions, such as transmission expansion planning (TEP) storage systems (ESSs) have been suggested improve flexibility amount. A proper optimization procedure is required choose an optimal solution Therefore, mixed-integ...
