Compared with static transmission network expansion planning (TNEP), multi-stage TNEP is more in line the actual situation, but modeling also complicated. This paper proposes a new method based on deep Q-network (DQN) algorithm, which can solve problem model. The main purpose of this research to provide grid planners simple and effective method, able flexibly adjust scheme without replanning. p...

This paper describes a methodology for transmission expansion planning (TEP) within a deregulated electricity market. Two objective functions including investment cost (IC) and congestion cost (CC) are considered. The proposed model forms a bi-level optimization problem in which upper level problem represents an independent system operator (ISO) making its decisions on investment while in the l...

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...

Previously we developed algorithm to obtain transmission reconstructions from emission data without transmission measurements. The optimal basis set of “knowledge set” was used to create an approximate attenuation map, and the expansion coefficients were estimated using optimization algorithm. Since a truncated expansion does not represent an image precisely, the estimated coefficients can be u...

In recent years the expansion planning problem has become increasingly complex. As expansion planning (sometimes called composite or integrated resource planning) is a non-linear and nonconvex optimization problem, researchers have traditionally focused on approximate models of power flows to solve the problem. The problem has also been split into generation expansion planning (GEP) and transmi...

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...

In planning studies, the conventional approach for steady state contingency analysis is to test all contingencies sequentially for evaluating system performance and reliability. This analysis consists of simulating outages of one or more generating units and transmission lines to study their effects on bus voltage, generator MVAR outputs and line power flows. But new challenges and uncertaintie...
