The project of distributed generation connection based on graded-controlling output power of generators

The paper describes the particularity of the mode of the distributed generation access to the power system but not allowed to transmit power to the system. A project is proposed that monitoring the load on user side in real time, and recording the load´s supply and demand, then dividing the generator´s power by the ratio of the generator and the user´s total load for several degrees. Once the load and generator output reach the critical balance, a part of the generators will be cut according to the degree, which can not only avoid the adverse-power protection acting, but also make a full use of the distributed generation to promote its economic efficiency.
