INTRODUCTION THE bulk of the Japanese market for monitoring and control systems for thermal and hydro power plants involves upgrades to existing equipment. The key requirements for this market are high reliability, the ability to undertake upgrade work quickly, an emphasis on compatibility with existing control equipment, and ease of maintenance. In markets outside Japan, meanwhile, demand for ...

In recent years, appearance of Distributed Generation (DGs) in power systems networks has provided important implications. Important advantages of DGs include increased reliability, loss reduction and improving voltage profile. In case of failure in the network, DGs can provide islands (isolated networks) resulting in continuation of supply loads and may reduce the number and/or duration of int...

This paper presents a hybrid particle swarm optimization based genetic algorithm and hybrid particle swarm optimization based evolutionary programming for solving long-term generation maintenance scheduling problem. In power system, maintenance scheduling is being done upon the technical requirements of power plants and preserving the grid reliability. The objective function is to sell electric...

The nuclear phase-out and the increased share of renewable distributed generation implicate new challenges for transforming the electric power system into an environmentally sustainable, reliable and cost-efficient system. An important component in transforming the electric power system is the reliable substitution of large controllable power plants by small generation units (photovoltaic syste...

This paper proposes a method for choosing the best coordinated expansion planning of generation and transmission systems considering an annual outage cost and a probabilistic power system reliability criterion (RLOLEGTS). The objective method minimizes a total cost which are not only an investment budget for constructing new generators and transmission lines but also an annual outage cost. Main...

in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...

The reliability assessment of distribution networks is one of the most important issues which the designers are challenging. In this paper, reliability assessment of a distribution network that include distributed generation is studied using Monte Carlo method. There are photovoltaics (PVs), wind turbines (WTs) and gas reciprocating engine (GREs) in this distributed generation. Normal and Weibu...

The paper presents new results of a recent industry supported research and development study in which an efficient framework for evaluating practical and meaningful power system reliability and quality indices was applied. The system-wide integrated performance indices are capable of addressing and revealing areas of deficiencies and bottlenecks as well as redundancies in the composite generati...
