Abstract
The electricity spot market can reflect the power supply and demand situation in real time through price signals, guiding users to shift peaks and fill valleys, and enhancing the level of new energy consumption. Gansu Province, one of the first pilot spot market provinces in China, has designed a bilateral spot market for generations and users. The power supply mode and grid operation mode will undergo changes according to the operation results of the power market to achieve the optimal allocation of power resources, thus posing a huge challenge to the original grid dispatching mode. The article analyses the dispatch management articulation model based on the high penetration of new energy grids in the power market reform, adapts the work focus after changes in the power market business, and explores efficient dispatching business processes for the power spot market to ensure a smooth transition of dispatching work and effective integration of the market business.
Highlights
By the end of 2020, the total installed capacity of wind power on the grid nationwide reached 281.53 million kilowatts, accounting for 12.8% of the total installed capacity of the national power supply and 28.6% of the installed capacity of non-fossil power sources [1]
Gansu Province is in the main area of renewable energy generation, with a rapid development of wind and solar power industries
As one of the first pilot provinces of the national spot market, Gansu Province is actively exploring a spot market system to promote the consumption of new energy, establishing a spot market mechanism for renewable energy penetration and launching a trial run of the spot market at the end of 2018, and so far Gansu has completed five settlement trial runs
Summary
By the end of 2020, the total installed capacity of wind power on the grid nationwide reached 281.53 million kilowatts, accounting for 12.8% of the total installed capacity of the national power supply and 28.6% of the installed capacity of non-fossil power sources [1]. The new stage of China's power system reform and spot market construction pilot will provide a new approach to the market-based large-scale consumption of new energy [2]. The advantage of low marginal cost of renewable energy will help to direct "load following source" and expand the space for energy consumption. It is difficult for the traditional power dispatching system to adapt into the Market-oriented reform, and new requirements have been put forward to adjust the departmental structure and priority of work in response to the changes in business. This paper presents the challenges of the market-based environment in which the high penetration of new energy is consumed, proposes a dispatch management transition method for the background of Market-oriented reform, explores efficient Market-oriented dispatch business processes, ensuring a smooth transition of dispatch tasks and effective integration of market business, to provide guidance for the dispatch management business of other high penetration new energy grids in a Market-oriented environment
