A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it). You can think of a relay as a kind of electric lever : switch it on with a tiny ...
Abstract. The configuration of energy storage helps to promote renewable energy consumption, but the high cost of energy storage becomes a major factor limiting its development.
