発明の名称 (英語) ENERGY SYSTEM AND ENERGY TRANSFER ADJUSTMENT METHOD
発明の概要(英語) In a community provided with multiple unit grids, this energy system (1) is an energy transfer network of single-unit facilities (10a-10f) that have a power load, wherein unit grids are each provided with a solar power generator (30) and form cooperative grids that supply power from local solar power generators to local power loads and that transfer power stored in mobile storage batteries mounted on electric mobile bodies (20) to and from other unit grids accompanying movement of the electric mobile bodies; the combinations of unit grids that form the cooperative grids change depending on the destinations of the electric mobile bodies, and thereby a virtual grid for power transfer is formed by multiple unit grids that are not in a fixed geographical positional relation.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional power energy systems have been unidirectional systems in which power (system power) transported (transmitted) via power lines from large power plants that generate power using fossil fuels is supplied to power consumers depending on consumption. In such conventional systems, the greater the transfer distance, the greater the power loss there between, and the greater the amount of power to be supplied relative to the amount of power ultimately required by the power consumer, so the greater the CO2 gas emissions. Reducing the discharge amount of CO2 gas, which is a main cause of global warming, is a challenge for humans. however, in order to reduce the discharge amount of CO2 gas in conventional systems, it is necessary for the supply side and the consumer side to perform measures separately, and there is a situation in which the measures have not been sufficiently advanced.
On the other hand, in recent years, local elimination and self-sustaining distributed small-scale power networks have been proposed that reduce the consumption of system power by installing a relatively small-scale power supply source in a limited region near power consumers and supplying power to the power consumers therefrom. In such a small power network, there is an advantage that the power loss therebetween is small due to the small distance from the power supply to the power consumer. In addition, the use of a power generation apparatus using renewable energy has been proposed as a power supply source in a small-scale power network, and in this case, it is expected that the discharge amount of CO2 gas can be reduced. Also, for countries who rely on the import of most fossil fuels, the utilization of renewable energy that can be served in the country without permanent depletion of resources is important to ensure a stable supply of energy.
However, the amount of power generated by power generation using renewable energy, such as photovoltaic power, solar power, wind power, and the like, inevitably varies greatly depending on various conditions in the natural world, such as weather conditions. Therefore, in conventional energy systems incorporating a power generation apparatus using renewable energy, a high-capacity stationary battery (secondary battery) is used to balance the power generation amount and demand (see Patent Document 1, for example). However, stationary storage batteries with large capacities suffer from high cost and large space is required for installation.
