There has recently been resurgent interest in energy storage, due to a number of developments in the electricity industry. Despite this interest, very little storage, beyond some small demonstration projects, has been deployed recently. While technical issues, such as cost, device efficiency, and other technical characteristics are often listed as barriers to storage, there are a number of non-...

This paper deals with the pumping storage system analysis. The water reservoir serves for daily and seasonal energy storage, thus basically solving the problem of energy storage, which is the biggest problem of wider use of renewable energy sources. The electrical energy produced in excess by the renewable energy system is converted in potential energy by pumping water to a higher elevation whe...

Thermal modelling and optimal design of a solar absorption cooling system are presented, and hourly analysis is performed over the period of a year. Three design parameters are considered, then the Real Parameter Genetic Algorithm (RPGA) is applied to obtain the minimum total annual cost. The optimization results show that the solar cooling optimum configuration needs 1630 square meter collecto...

In the Ontario power system, almost all coal power plants have been recently closed. The major power generation in Ontario is currently provided by nuclear power plants (base-load generation). Additionally, wind generation typically is maximum at night, a time period when the demand is minimum. This raises the question whether energy storage systems (ESSs) should be deployed in Ontario to shift...

This paper considers how power-based distribution tariffs encourage electricity end-users to invest in energy storages to reduce their peak loads. The study uses actual automatic meter reading (AMR) data from 30 000 customers the annual electricity consumption of which is less than 50 MWh. The customers locate in the area of a Finnish distribution system operator (DSO) operating in an urban env...

The demand for comfort cooling is increasing very quickly around the world, e.g. due to improved living standards. At present, air-conditioning is consuming large amounts of electricity, often during hours of peak power demand. Also, a major part of the electricity around the world is produced from fossil fuels, and thus the threat of global warming, caused by increasing emissions of carbon dio...
