[Introduction] Under the new environment of power market, the power system planning contains more variables, constraints, planning objectives and complexity. The uncertainty variables include load, power supply, power flow, equipment retirement, policy, social economy, bussiness mode, investment profit, etc. It is necessary to establish appropriate plannnig model based on the complexity mentioned above. The research methods of the whole power planning and means need to be further optimized. [Method] Firstly, this paper reviewed the status quo of the more mature power markets in Australia, PJM in the United States, Europe and other foreign countries, and analysed their power system planning models and methods. [Result] Combined with the current situation of Guangdong power market development, this paper optimized the planning method of Guangdong power system under the power market environment. Not only did it give suggestions for optimizing and adjusting the institutional mechanism of power planning work, but also complemented and improved the five aspects of planning input, project classification, scenario study, grid economic efficiency assessment and uncertainty analysis according to the traditional Guangdong power system planning method. [Conclusion] Under the new environment of Guangdong spot market of energy, by establishing a reasonable power system planning and evaluation system, it can be beneficial to rationalize allocation of power sources, achieve coordinated planning between network sources, and better adapt to the future development of the power market.
