Abstract:
Existing pre-evaluation methods for high-voltage distribution network project do not consider the power supply company’s investment ability and the overall techno-economic status of the whole high-voltage distribution network, which may cause great investment risk and "repetitive investment". Moreover, these methods evaluate the local network influenced by the project based on a single rather than sequential load status, which cannot reflect the local network’s condition from the perspective of the whole year. Therefore, the proposed method firstly evaluates the company’s business status(CBS) and the overall situation of the whole network(OSWN). Then the whole year’s sequential operation state of the local network is simulated and evaluated. The simulation results show that the method can reflect the influence of CBS, the OSWN and the project’s improvement effect from the perspective of the whole year.
