We study the reservoir management problem in hydropower plants, and propose operating policies to maximize the average annual energy generation or the average annual revenue. Under revenue maximization, our policies allow for short-term electricity price variations to be incorporated into the long-term plan. First, we provide a detailed review of hydropower plant operation, focusing on implicit stochastic optimization approaches and integration of energy price variations in reservoir management. Then, we explain non-linear programming models that we developed for obtaining operating policies with different characteristics. We evaluate and compare the operating policies through a case study. Policies characterized by dynamic end-of-month storage levels are shown to perform much better than the policy with an optimal static end-of-month storage level, and it has been further shown that the dynamic policies perform quite close to the theoretical upper bound. Finally, we show that maximizing the average annual energy and maximizing the average annual revenue objectives yield considerably different operating policies and using one policy in place of the other may result in significant loss of benefit or resource.

Technical and economic assessment of fixed, single and dual-axis tracking PV panels in low latitude countries
Bahrami, Arian; Okoye, Chiemeka Onyeka; Atikol, Ugur (Elsevier BV, 2017-12-01)
This study aims to contribute towards developing a sustainable roadmap for electrification program via solar energy deployment in 21 low latitude countries (0-15 degrees N) with limited access to the grid. Firstly, the available electrical energy from fixed, single and dual-axis solar tracking PV panels is demonstrated using a case study of nine selected locations in Nigeria. The annual electrical energy for the locations from a fixed 1-kW PV panel tilted at an optimal angle ranges from 1485 to 2024 kWh, wi...
Comparisons and critical assessment of global and diffuse solar irradiation estimation methodologies
Karaveli, Abdullah Bugrahan; Akınoğlu, Bülent Gültekin (Informa UK Limited, 2018-01-01)
Defining better methodologies of accurate predictions of the amount of monthly mean daily global and diffuse solar irradiation exposed is of utmost importance in order to determine the potential for utilizing the solar energy. This study compares and discusses the main methodologies, databases, and software that are used in estimating the solar irradiation to be used for the short- and long-term performances and feasibilities of solar energy systems, especially photovoltaic power plants in Turkey, and addre...
Development of new monthly global and diffuse solar irradiation estimation methodologies and comparisons
Karaveli, Abdullah Bugrahan; Akınoğlu, Bülent Gültekin (Informa UK Limited, 2018-01-01)
In assessing and deciding the prediction schemes of solar irradiation countrywide, better the accuracy means better the management of energy transition toward renewables. Consequently, the present study is on the development of new models to make the most accurate possible estimations of the global and diffuse solar irradiation based on ground measurements. Such analysis produces the most accurate estimations for the input of solar energy systems. This is utmost significant for deciding the investments on s...
The potential and economic viability of wind farms in Zimbabwe
Samu, Remember; Fahrioglu, Murat; Ozansoy, Cagil (Informa UK Limited, 2019-09-29)
Wind energy potential in Zimbabwe so as to curb for the energy deficit is assessed in this study. The frequency of load shedding in Zimbabwe has increased; this is due to insufficient energy generation and rising energy demand. Wind energy is intermittent and these fluctuations might lead to an unreliable system so the wind turbines are going to be grid-connected, in the event of a deficit from the wind system, the grid will supply. Conversion of wind resources in 28 different locations scattered all over Z...
Solar generated steam injection in heavy oil reservoirs: A case study
Afsar, Cansu; Akın, Serhat (Elsevier BV, 2016-06-01)
Combination of solar generated steam technology and enhanced oil recovery (EOR) techniques have attracted a great deal of attention due to its positive impact on economics and on the environment. Solar steam project has already proven itself as it can reduce both gas consumption and CO2 emissions by up to 80%. However, operational issues as well as geographical factors (i.e. terrain suitability, drill sites and future field development plans) may affect solar EOR operations. In this study, a heavy oil field...
