Transmission network expansion planning (TNEP) is a basic part of power network planning that determines where, when and how many new transmission lines should be added to the network. So, the TNEP is an optimizing problem in which the expansion purposes are optimized. The Artificial Intelligence (AI) tools such as Genetic Algorithm (GA), Simulated Annealing (SA), Tabu Search (TS), Artificial n...

Optimal Power Flow (OPF) has been widely used in power system operation and planning. This paper presents Differential Evolution (DE) method to solve optimal power flow in power system incorporating a powerful and versatile Flexible AC Transmission Systems (FACTS) device such as Unified Power Flow Controller (UPFC). Unlike other FACTS devices, UPFC has a great flexibility that can control the a...

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...

In regions with high penetration of Distributed Energy Resources (DER), grid congestion is mostly caused by power feed-in generators. this context, conventional approaches for solving the problems are Active Power Curtailment (APC) DER and reinforcement. wake increased generation, it not only interest how to obtain reinforcement, but also consider APC during planning. The challenge such plannin...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

Today, the electricity power system is the most complicated engineering system has ever been made. The integrated power generating stations with power transmission lines has created a network, called complex power network. The reliability estimation of such complex power networks is a very challenging problem, as one cannot find any immediate solution methods in current literature. In this pape...

The Western region comprising the states of Madhya Pradesh, Maharashtra, Gujarat and Goa is geographically the largest in India with installed capacity currently around 28000 MW. Peak demand currently around 24000 MW is projected to touch 45000 MW by end of the decade. A large chunk of the increase will have to come from thermal generation located in Eastern Madhya Pradesh and the power will be...
