Design of micro-grid with biogas power generation

摘要

As a distributed renewable energy, biogas power generation have many advantages including high efficiency, low investment cost, energy-saving, and high reliability. In this paper, a mathematical model of micro-grid has been introduced and multi-complementary micro-grid operation strategy has been analyzed.The optimal ratio of the installed capacity of renewable energy in micro-grid has been presented, considering the cost and energy consumption. An example is used to prove the feasibility of the proposed design method.
