Distributed generation sitting and sizing planning based on the locational marginal capacity cost and timing characteristics of distribution network
The marginal capacity cost of distribution network expresses the change of the investment cost of power supply caused by the capacity change of power supply equipment due to the increase of the load or the distributed generation (DG) access the distribution network. According to the distribution network open loop operation, the sensitivity coefficient matrix is built by the sensitivity method, the locational marginal capacity cost(LMCC)in the distribution network is calculated, and considering the change of LMCC according to the actual situation, the DG benefit evaluation is divided into customer owned DG and DG configuration of the power department. This paper focuses on the planning of multi-type DG sitting and sizing in DG configuration of power department, and takes into account the timing characteristics of the load and the multi-type DG .Finally, the MATLAB software is used to calculate the LMCC value in the IEEE33 node distribution network, and the DG planning considering the timing characteristics is carried out by using the particle swarm optimization algorithm, and the rationality of the model and method is verified.
