GR1010329B - Mechanical energy storage - Google Patents

Abstract

The whole proposal is based on the working principle of the pendulum clock, with a weight. We get the electricity they generate e.g. the photovoltaic panels and connect an engine connected to reducers, rotating a drum, adapted to a height construction, in which a wire rope with a weight is rolled. At the end of the "haircut" we stored electrical energy in engineering. In electricity demand we release the weight and with gravity we convert mechanical energy into the movement of a generator to generate electricity.

Description

Storage of produced electricity, from renewable sources, in the form of mechanical energy and performance in electricity, when requested.

Description.

The invention refers to the storage of electrical energy in the form of mechanical energy and consists of a motor (M) - generator (G), (dual use), winding drum, wire rope, weight.

In the production of electricity, its storage is considered very important. Until now, storage stations have been based on batteries or pumped storage systems. Both forms of storage have their weaknesses. Batteries currently do not have the required capacity, while pumped storage systems are essentially small hydroelectric plant constructions and only applicable as large-scale storage plants in the interconnected system.

An advantage of this invention is that the areas and useful water resources of pumping and saving systems are not required and large-scale storage stations can be created, as well as scattered storage stations.

The whole proposal is based on the principle of operation of the pendulum clock, with a weight. We take the electricity produced by e.g. the Photovoltaic panels and we feed an electrical energy storage complex, consisting of: a motor (M) - generator (G), connected to a reducer, which rotates a drum, on which a wire rope is wound with a weight and all this mounted in a structure as height. Powered by current, the motor (M) - generator (G) rotates the drum, in which the wire rope is collected with the weight. At the completion of the winding "tuning", we stored electricity in the form of mechanical energy. When there is a demand for electricity, we release the weight and with gravity the rotation of the engine (M)-generator (G) is achieved, which injects electricity into the DEDDIE network.

Example implementation

The application of renewable energy sources (sun, wind) alone is not the solution for the country's energy needs. The problem in generating electricity from RES is the dependence on weather conditions. For this, the main issue is the storage of the generated electricity.

In Western Macedonia for "Clean Energy" production, the emphasis is on the construction of photovoltaic parks, with expressed interest in the construction of ~2GW, of which ~0.4GW are under construction. The scientific opinion of the Geotechnical Chamber of Greece characterizes the anarchic dispersion of photovoltaic parks as harmful. The correct location of the installation of photovoltaic energy production plants should, in terms of the general design of the production direction, take into account: a) high productivity agricultural land, b) pasture lands and c) simple agricultural land (low productivity). Also important is the preservation of forest and natural areas. In addition, the Municipality of Kozani highlights the need to utilize existing or unfinished infrastructure.

Based on the above recorded positions of the agencies, I propose the exploitation of the infrastructure of the abandoned AIS Ptolemaida. On chimneys and cooling towers, install vertical photovoltaic panels, covering the side facing South. Also on the roofs of existing buildings, horizontal deployment of photovoltaic panels. In addition, there are floor areas within the Steam Power Station for the installation of photovoltaic panels. Applying the patent to PPC facilities: connecting the electric power produced by the photovoltaic panels to the motor (M) - generator (G) of each electrical energy storage assembly, which are placed at the top of each of the chimneys or cooling towers. When the motor (M)-generator (G), is supplied with electricity, it rotates the drum, in which the wire rope is collected with the weight on top "tuning". Then we have accumulated stored mechanical energy. At each demand, to convert the mechanical energy into electrical energy, we release the barium and with gravity, rotation of the motor (M) - generator (G) is achieved, which injects electric current into the grid.

The patent can also be adapted to wind turbines, taking advantage of the height of the pylons.

Claims (1)

Storage of produced electricity, from renewable sources, in the form of mechanical energy and performance in electricity, when requested. Claims Claim No 1 Until now, the ways of storing electricity have been based on batteries or pumped storage systems. My proposal develops this with pumped storage systems, which are in a way small hydroelectric plants. The assembly for the storage of electrical energy in mechanical form, according to claim 1, is characterized in that a motor (M) - generator (G), raises a weight "tuning" in height, (instead of pumping water from a lower to a higher water reservoir). At each demand, to convert the mechanical energy into electrical energy, we release the barium and with gravity a motor (M) - generator (G) rotation (unwinding) is achieved, which injects electric current into the grid. Regarding the technical part, it can be used as a large-scale storage station in the interconnected system but also as dispersed storage stations at the distribution network level.
