Forecasts of hydrological variables at a medium-range horizon, from one to two weeks, are useful to operate reservoirs, especially if these are used for hydropower generation and are constrained due to multiple water uses. In the present study we investigate the use of medium-range scenarios of reservoirs inflow for a decision making procedure related to a reservoir operation in the Doce River ...

Forecasts of hydrological variables at a medium-range horizon, from one to two weeks, are useful to operate reservoirs, especially if these are used for hydropower generation and are constrained due to multiple water uses.

A six-dimensional nonlinear hydropower system controlled by a nonlinear predictive control method is presented in this paper. In terms of the nonlinear predictive control method; the performance index with terminal penalty function is selected. A simple method to find an appropriate terminal penalty function is introduced and its effectiveness is proved. The input-to-state-stability of the cont...

Abstract Most countries mitigate climate alter impacts by deploying renewable energy to decarbonize their system. One of the emerging options is integration floating photovoltaic (FPV) and hydropower. The FPV has higher efficiency helps reduce evaporation offset hydropower production during dry season. Conversely, can overcome intermittent solar due its flexibility. Our study aims estimate pote...

Ice formation and related processes in rivers and lakes/reservoirs influence the operation of hydropower plants in cold regions. It is a matter of interest to the scientific community and hydropower operators alike how existing ice effects and problems will manifest themselves in a future changed climate. In this paper, we use different modeling results to investigate future freshwater ice cond...

S. Jamshid Mousavi (corresponding author) M. Shourian Department of Civil Engineering, Amirkabir University of Technology (Tehran Polytechnic), Tehran, Iran E-mail: [email protected] A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project’s firm energy yield. Particle swarm optimization (PSO) i...

Among the energy targets of Vietnamese government, solar is expected to become main source renewable in future. Solar moving forward, with Vietnam outstripping Thailand and becoming country that installed largest capacity power generation Southeast Asia, reaching 16,362 MW new installations December 2021. In this study, we have experimentally analyzed designed a 47.5 grid-connected photovoltaic...

Here we translate the impacts of climate change on hydropower generation, and discuss implications on greenhouse gas (GHG) emissions and operation in California. We integrate a model of major surfacewater reservoirs with an electric grid dispatch model, and perturb it by projected runoff based on representative concentration pathways (RCP4.5 and RCP8.5). Results show that climate change and var...

This paper presents a new methodology to maximise the income and derive the optimal end of day storage of closed-loop and daily-cycle pumped-storage hydropower plants. The plants participate in the day-ahead energy market as a price-taker and in the secondary regulation reserve market as a price-maker, in the context of the Iberian electricity system. The real-time use of the committed reserves...
