Operation of a system having both hydro and thermal plants is far more complex and is of much more importance in a modern interconnected power system. The objective of the STHS problem is to optimize the electricity production, considering a short-term planning horizon. This paper presents an extensive review of a short term hydro thermal scheduling problem. The paper demonstrates results of va...

Economic needs and the ongoing liberalization of European electricity markets stimulate the interest of power utilities in developing models and optimization techniques for the generation and trading of electric power under uncertainty. Utilities participating in deregulated markets observe increasing uncertainty in load (i.e., demand for electric power) and prices for fuel and electricity on s...

Institut de Recherche d’Hydro-Québec for modeling and simulating wind power plants for power system studies. The electromagnetic transient model of a wind generator using a doubly-fed induction generator is presented. Modeling techniques for simulating large wind power plants are described. Model validation using field measurements and simulation study are presented. Real-time simulation of 25 ...

Electrical power system is one of the largest and most crucial engineering systems which spreads everywhere in countries to supply electricity for hundreds of millions of consumers from hundreds of thousands of producers. In its more than one century history, the development of the power system proceeded through evolutional stages from local isolated networks with small-scale load and generatio...

In an interconnected power system, as a power load demand varies randomly both area frequency and tie-line power interchange also vary. The objectives of load frequency control (LFC) are to minimize the deviations in these variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zero. In this area of energy crisis, renewable energy is the most prom...

The latest trend in generating power for industrial and domestic purposes is the hybrid power generation using non-conventional energy sources. The non-conventional energy sources are the renewable sources that can be utilized again after every use and also whose supply is abundant in nature. This paper presents a new system configuration of the front-end rectifier stage for a hybrid wind/photo...

The problem of determining the optimal hourly generation in hydrothermal power plants and total thermal generation is studied. A multi reservoir cascaded hydro-electric system with a non-linear relationship between water discharge rate, net head and power generation is considered. PSO technique has been motivated by the behavior of the organisms such as fish schooling and bird flocking. The ind...

The three renewable energy technologies discussed in this paper are based on water, but differ markedly in terms of the size of the available potential resource, the maturity of the associated conversion technologies, the extent to which they have been exploited to date, and the current research effort being devoted to their future development. Hydro-electricity and tidal power are both very ma...

Central Electricity Authority have completed the preliminary ranking study of hydro electric schemes to harness the balance hydro electric potential in the country. Hon’ble Union Minister of Power Shri Suresh Prabhu released the report on "Preliminary Ranking Study of Hydro Electric Schemes" on 5th February 2002 at the International Conference and Business Meet on Non-fossil fuel generation org...

The job of automatic frequency regulation is achieved by governing systems of individual turbine generators and Automatic Generation Control (AGC) or Load frequency control (LFC) system of the hydro power plant. This seminar report addresses a comprehensive literature survey on load frequency control in hydro power plant. The report is aimed to present the various control and structural schemes...
