The paper analyses the coordinated hydro-wind power generation considering joint bidding in electricity market. impact of mutual strategies on market prices, traded volumes, and revenues has been quantified. coordination assumes that hydro is scheduled mainly to compensate differences between actual planned wind outputs. potential this achieving utilizing explored. equilibrium asymmetric compan...

This paper describes the dynamic performance of two area interconnected hydro-hydro power systems when subjected to 1% step load perturbation. For this present study, the system is incorporated with conventional Proportional-Integral (PI) controller and Fuzzy Logic Controller (FLC). The dc link is used as system interconnection in parallel with ac tie-lines. The dc link is considered to be oper...

Small Hydro-power Plants (SHP) are an important source of electricity in many countries. However, little is known about SHP in Kenya. This paper reviews the status, challenges in implementation of SHP and prospects for future development of SHP in Kenya. The paper shows that SHP has not yet fully utilized the available hydro-power potential. The challenges associated with SHP development should...

This paper presents a simple multi-objective control technique for cascaded hydro power plants, based on a centralized distributed power control system and local water level controllers. This effective power management solution enables to guarantee the generation program following with a very good accuracy, to participate to power-frequency Ancillary Services with the dynamic performance requir...

6.1 Best Practices in Operation & Maintenance of Hydro Power stations shall be such that by following such procedures, the downtime of individual generating Unit & Plant should be minimum. The operational reliability of the generating units of the hydro power stations shall be such that whenever the grid demands, it should be available for generation. Some of the aspects, which can be taken int...

Historically, the optimal production of hydro power plants was determined once day ahead. Today, many regulatory requirements in the German electricity market make this process much more complex: Power plant operators are committed to report information on planned production and even on provision of balancing energy of each single generator to transmission system operators. As soon as a deviati...

The hybrid energy systems are required to operate stably in different time scales. Previous studies on the stability carried out under unrealistic assumption of discontinuous Therefore, a second scale model for is presented this study. To overcome possible uncertainty caused by assumption, new method introduced analyze power fluctuations system considering hydroelectric station (HPS) and PV-win...

Renewable source based micro-generations such as wind and hydro offer the best potential for emission free power in future power systems. This paper investigates the technical issues related to stable and autonomous operation of a micro-grid system consisting of renewable power sources. A small hydro generation unit and a wind farm are the main renewable power generation units in the proposed m...

This paper presents a hydraulic hybrid vehicle drive train to improve the fuel efficiency of a passenger car. The developed hydro-mechanical drive train enables independent control of the torque at each wheel. The motivation for developing this drive train is a hydraulic hybrid vehicle test bed for the Center for Compact and Efficient Fluid Power at the University of Minnesota. The hydro-mechan...
