Modeling of Distributed Generation in Power Flow Calculations on Distribution Networks

Distributed Generation that is usually installed in the client or near them is a kind of power equipment whose capacity is generally small in the tens of kilowatts to tens of megawatts, which becomes a hot research area at home and abroad in recent years. The method for power flow calculations on distribution networks face new challenges because of the access of distribution generation, while, modeling of distribution generation is the basis and precondition for the research of power flow calculations on distribution networks with distributed generations. The article studies the modeling of distributed generations in power flow calculations, anylies most distributed generation forms, focuses on the interpretation of the principle and essence of them, and establishes theoretical models apply to the flow calculations. The modeling lay a solid theoretical foundation for the power calculations on distribution networks with distributed generations.
