Requirement of Production Simulation of DC Distribution Network Containing High Renewable Energy

Renewable energy power generation connected to the DC distribution network, converter station capacity, renewable energy installed capacity and renewable energy operation mode are the primary factors that affect the maximum consumption of renewable energy. Unreasonable converter station capacity and renewable energy installed capacity planning and configuration will result in excessive renewable energy installed capacity, resulting in abandonment of wind and light, or too small installed capacity to make the converter station with full using. The renewable energy power generation operation mode strategy directly affects the DC distribution network transmission capacity and the regulation capacity of the energy storage station, which in turn affects the consumption of renewable energy power generation. The paper studies relevant time series modeling methods of wind and PV power generation, and proposes the technical requirements for optimizing the power generation operation mode considering the hybrid of multiple types of renewable energy and the DC distribution network, so as to achieve maximum consumption renewable energy, and to ensure that the power of renewable energy can be “controlled and consumed’', and ultimately ensure the stable operation and safe of renewable energy and the DC distribution network. The paper results will provide support for the future planning of the local consumption of a high proportion of renewable energy, and will effectively guide the planning and design of renewable energy and DC distribution networks.
