Security Boundary Based Research Idea on Planning of Distribution Networks with High Renewable Penetration
摘要
Abstract
The security boundary based planning idea and research scheme for the distribution system with high penetration of renewable energy generation are proposed.Firstly, the problems of the distribution network in China caused by integration of renewable energy generation are discussed.It is pointed out that the system security is the bottleneck limiting the high proportion of renewable energy generation while the security boundary, which is an effective way to break through the limitation, can describe the maximum operation range of a system when N-1 guideline is considered.Then, it has been found that the model, characteristics and mechanism of security boundary will significantly change in the scenario of high proportion of renewable energy generation: the range of security boundary will transform to a total-quadrant region from a single-quadrant region;the function and security characteristics will differ a great deal with an increase in penetration.Thus, it is necessary to determine the critical penetration rates which will cause essential changes of security.Finally, a security boundary based planning idea is proposed: 1) The network configuration will be selected based on the index of security boundary, such as shapes, and the controllable components, such as energy storage and active load, should be optimized.2) The two planning methods for the scenarios of high-load density in urban area and rich renewable energy in rural area.3) The generalized source-load index is developed by referring to the load ratio, to guide the practical planning.4) New test system and simulation platform for distribution network planning is developed.关键词
