TL;DR: In this article, a secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources by using a power distribution panel to selectively bypass the secondary system and disconnect non-vital loads when primary power is not available.
Abstract: A secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources. Primary power is rectified and connected to a DC bus, an AC generator has its output rectified and connected to the DC bus, and a storage battery is also connected to the DC bus. Current on the DC bus is inverted to AC to provide an uninterrupted power supply. The system is connected to a household electrical system by a power distribution panel which can be installed in a home prior to the secondary power system and can facilitate installation of the secondary system. The distribution panel can selectively bypass the secondary system and can disconnect non-vital loads when primary power is not available. The generator is powered by an engine using gasoline, natural gas or water, which can also power other systems, such as air conditioning, with exhaust heat or rotary motion.

TL;DR: In this paper, a new method of power flow calculation considering FACTS devices is developed from a view of general approach of nonlinear system, which can also be used when there are some other nonlinear devices in a system.
Abstract: A new method of power flow calculation considering FACTS devices is developed in the paper from a view of general approach of nonlinear system. The power flow equations of a power system with FACTS devices are presented. This method can also be used when there are some other nonlinear devices in a system. Testing results show that this method costs less time in power flow calculation than other methods. The power flow control range of UPFC in a power system is employed in the discussion. Examples are presented to show and verify what this paper specifies.
