According to need of non-stop supplying,an intelligent optimized scheme of double-power supply automatic switch system is proposed with microcontroller P89c591 as main chip by sampling and comparing in this system.

In fact,there are many factor influence the accuracy of maximized demand such as demand error,setting demand,adjusting meter-reading date as well as load and co-operation of double-power supply consumers.

There are few analysis on the impact of bidding modes in electricity auction market on both middle-and small-scale generation companies and power source structure optimization in existing literatures,and there are some discrepancy in electricity market operation results under monopolistic competition market structure and complete competition market structure.

To scientifically work out the development plan of power source in Guangdong, China during the eleventh Five-Year Plan, and to promote the sustainable development of Guangdong s power industry, this paper makes a discussion on power source structure and layout, development tempo and scope of power source, and the coordination between power and other sectors.

Investigation on optimization of power sources structure in Guangzhou City;
