- Many communities have their own renewable energy generators to reduce long-distance power transmission losses and to decrease greenhouse gas emissions. However, in high power demand regions, power transmission congestion is often occurred when abundant renewable energy is generated and injected into the grid, which affects the security of transmission lines and power grids. In this paper, the congestion was caused by redundance power produced by community renewable energy generators. Double-layer power allocation strategy was presented to optimize the issue. In scheduling layer, linear optimization was used to allocate power flow, and fairness was also considered. In community layer, inverters were launched or stopped in turn by operation time to minimize the number of working units and to reduce costs. 6 communities with different power production were chosen for the simulation to justify the strategy. The results show the Double-layer strategy can alleviate congestion and increase the average utilization rate of inverters.
