A hybrid isolated microgrid is proposed, including PV power, diesel generator system, load and other subsystems.. Based the equivalent circuit and output characteristics of photovoltaic cells, PV model has been established and maximum power point tracking(MPPT) has been implemented to make full use of solar energy. Diesel model has been established, base on it PID load frequency compensation control...
In this paper, a micro grid price mechanism is discussed and optimised. Operators can increase the consumers's profile under step-price environment. With a novel low-carbon strategy designed in this paper, consumers make ones own decision whether to buy or sell energy with what price. By using this strategy, energy distribution can be optimised and the utilization of clean power will increase. A simulation...
Distributed energy resources and energy-storage units are parallel connected through converters in a DC bus microgrid. Current sharing is a basic requirement for microgrid and many current sharing methods are proposed. Distinct from those methods like the average current method, centralized method and master-slave method, the droop control method does not need any interconnections between the converters...
