An apparatus of solid oxide fuel cells (SOFC) is provided. The SOFCs generate power and are grid-tied. The apparatus comprises a power-generating side; and a grid-connecting side using an elementary household power management. The apparatus solves problems like low voltage, high current, voltage oscillation, voltage dips, long generator-starting time, etc. The apparatus is not only used as a stable power supply (base load), but also helps adjust the regional peak electricity demands. The features include the following: 1. A grid is tied, where output power does not pass through a direct-current boost converter and, thus, has no loss from it. 2. Injures, including voltage oscillation and sudden unloading after dumping, are reduced for avoiding further damages to cell sheets. 3. With the coordination of elementary power management and the integration of grid, the limitation of long-awaiting generator-starting time is crossed out and convenience of immediate power use is achieved.

A smart grid monitoring device with multi-agent function is provided, which may include a measurement module, a communication module and a control module. The measurement module may measure at least one real-time electric signal of a power transaction system or an electric unit. The control module may execute a self-developed program to provide at least one agent functionality and then control the electric unit according to the at least one real-time electric signals measured; the communication module can transmit the at least one real-time electric signal to other monitoring devices or the main computer of the power dispatch transaction system, and can control the electric unit according to the at least one electric signal. The communication module can receive electric demand signals from the power company or other monitoring devices of the power dispatch transaction system via the main computer to execute the electricity transaction with the bidding mechanism.
