Discussion on advantages and disadvantages of distributed generation connected to the grid

摘要

With people attention to sustainable development and environmental pollution, distributed generation(DG) technology with its unique environment and economy raises more and more concern. The rapid development of DG technology results in large-capacity distributed power connected to the grid, but DG affected by natural conditions will can not output power continuously and stably. And DG usually is incorporated into the electric power system at the distribution networks side, which will cause the system stability problems increased. In order to fully play the role of distributed power, avoid the adverse effects of its existence, it is necessary to study in-depth on DG and the technology of its connected to the grid. In this paper it is researched and analyzed for problems brought by DG connected to the grid and put forward the corresponding solution.
