The aim of this work is to study the primary control system of a hydropower plant in isolated mode. The power plant is modeled by differential equations and results are compared to field data from an actual hydropower plant, presenting deviations lower than 1.0%. The study of primary control system is conducted in order to define useful sets of parameters for controllers. Four controllers are s...

The need to mitigate climate change and reduce carbon emissions has resulted in an increasing demand for the transition from fossil fuels renewable sources of energy. Hydropower, particular, emerged as a prominent extensively developed source energy recent decades. This specific harnesses kinetic falling or fast-flowing water generate electricity. Despite being dependable, adaptable, cost-effec...

This study aims to investigate the different management policies of multi-reservoir systems and their impact on the demand supply and hydropower generation in Great Karun River basin. For this purpose, the semi-distributed simulation-optimization  model of the Great Karun River basin is developed. Also, the multi-objective particle swarm optimization algorithm is applied to optimize the develop...

Introduction According to the Swiss Energy Strategy 2050, which takes into account the phase out of the existing nuclear power plants, the mean annual hydropower production must be increased by 1.5 TWh/a under present framework conditions, eventually reaching 3.2 TWh/a if conditions are optimized (SFOE, 2016). In view of environmental and socio-economic constraints, this foreseen increase is ex...

This paper presents results from a seismic vulnerability analysis of the components of hydropower systems in Canada. A number of dams and their associated components (hydropower plants, switchyards, transmission towers, and supplementary equipment) at selected locations in western and eastern Canada were analyzed in the study. The seismic vulnerability for a given hydropower component was estim...

Electricity grid interconnections have played a key role in the history of electric power systems. The greatest benefits of interconnection are usually derived from synchronous AC operation, but this can also entail greater reliability risks. An alternative energy supply to assist the main power stations in future is expected from renewable energy sources based on distributed generation like Sm...

This Case Study focuses on a cooperation mechanism developed in Costa Rica between La Esperanza Hydropower Project (downstream water user) and the Monteverde Conservation League, a conservation NGO that owns most of the hydropower plant's upper catchment. The objective of the mechanism is to ensure the conservation of forest cover where it already exists, since forests are perceived to provide ...

Renewable energy provides 20% of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It provides almost onefifth of the electricity in world. Hydropower is produced in more than 150 countries. The main objective of this paper is modelling and analysis of the effects of the power system stabilizer (PSS) for load frequency control (LFC) system ...
