application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

Hydroelectric energy is a major source of renewable electricity in the world. The industry is continuously searching for ways to improve the efficiency and reliability with which it produces energy. The turbine governor plays vital role in keeping frequency constant. Here we proposed a fuzzy approach to turbine governor by utilizing human experience. The simulation model of Hydro Power Plant (H...

The low head hydro power plant in Wettingen, Switzerland, is in operation since 1933 and no effective cam optimization has been carried out up to now. The goal of the measuring campaign was to provide data enabling an economic study for a retrofit and upgrade project of the plant and the measurement of the efficiency improvement of turbines after refurbishment. The contribution discusses cam te...

recently, transverse flux permanent magnet generators (tfpmgs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowest har...

This paper presents a profit-based model for short-term hydro scheduling adapted to pool-based electricity markets. The objective is to determine a feasible operation of a set of coupled hydro units belonging to a small or medium-size hydroelectric company. The company is assumed to be price-taker, and therefore, market prices are considered exogenous variables and modeled via scenarios. In ord...

A decision support system is presented that addresses optimal unit dispatch and load allocation in a multi-unit hydroelectric plant. The concept behind the optimization approach is explained. Estimates of the improvements this system can provide over existing plant operational methodologies are provided. Actual use of this system has provided gains of over 2% in plant performance.

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...

This paper presents a comparison between a decentralized and a distributed model-based predictive controller on a hydro power valley (HPV) benchmark recently proposed. The HPV is composed by three lakes and a river that is divided in six reaches that terminate with dams equipped with turbines for power production. The lakes and the river reaches are connected in three different ways: by a duct,...

A data-driven approach for maximization of the power produced by wind turbines is presented. The power optimization objective is accomplished by computing optimal control settings of wind turbines using data mining and evolutionary strategy algorithms. Data mining algorithms identify a functional mapping between the power output and controllable and non-controllable variables of a wind turbine....
