This document deals with the need for construction of new pumped storage hydroelectric power plants. Special attention has been dedicated mainly to the search for suitable locations to place PVEs, including utilization of new options of their placement.
This paper addresses a new fully green solar-pumped hydroelectricity storage system as a way to effectively store the energy through the gravitational potential energy of stored water and uses it during peak demand hours. Electric energy produced by the photovoltaic system will be used to pump water during the day from a lower reservoir, in our case the Litany River, to an upper reservoir which is...
Significant advances have been made in automation technology allowing systems to shift electricity consumption from peak periods to off-peak periods. Load shift projects have been implemented throughout South Africa for their electricity cost saving potential. This study shows how these load shift projects also reduce the carbon dioxide production at power stations by 91 kg/MWh shifted. This reduction...
Water is scarce resource with uncertain availability. Hence finding an optimal production schedule for hydro producer is usually a complex task and it is necessary to carefully balance the timing of water use. This paper addresses the self-scheduling problem for a price-taker hydro producer. The goal is maximizing the profit of a hydro producer through participating in the day-ahead energy and ancillary...
Generation scheduling is an important component of power systems operation in a market environment. Electricity demand in different areas depends on local marginal prices in the wholesale market. The paper presents a model for mid-term optimization of electricity generation in the hydrothermal power systems. The scheduling aims to minimize total production cost. Elasticity of consumer demand is taken...
To limit the impact of the intermittence of wind power, a water storage ability of the hydraulic storage plant combined with a wind power plant, called the wind-hydro power system (WS), is used. The main objective is to limit the active power output variations of wind energy resource taking into account the grid needs and the available stored energy. The problem is formulated as an optimization problem...
