Flexible Power Electronic Transformer for Power Flow Control Applications

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

Optimization of Hydro-Power Plants for Generation

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.

Hydro-Storage Subproblems in Power Generation: An Approach with a Relaxation Method for Network Flow Problems

Mathematical models for the electricity portfolio management of a utility that owns a hydro-thermal generation system and trades on the power market often lead to complex stochastic optimization problems. We present a new approach to solving stochastic hydro-storage subproblems that occur when stochastic Lagrangian relaxation is applied to solving such models. The special structure of such hydr...

Design of Micro - Hydro - Electric Power Station

Micro-hydro-electric power is both an efficient and reliable formof clean source of renewable energy. It can be an excellent method of harnessing renewable energy from small rivers and streams. The micro-hydro project designed to be a run -of-river type, because it requires very little or no reservoir in order to power the turbine. The water will run straight through the turbine and back into t...
