Power generation plan considering priority generation under power spot market environment

来源: | 作者:佚名 | 发布时间 :2023-12-06 | 285 次浏览: | Share:

It is worth noting that under different situations in this example, the cash market income of power generation enterprises and the cash market expenditure of market users are positive. If the income and expenditure of the spot market are negative, the incentive effect of electricity plan formulation on the trading willingness of market players may be further enhanced.

It can be seen that in the implementation of the generation plan formulation method in the market environment designed in this paper, power generation enterprises and power users are inclined to fully sign medium - and long-term contracts on the premise of passing the safety check in order to maximize the unit market revenue. This trend has nothing to do with medium - and long-term contract prices, which to a certain extent avoids the behavior of malicious pricing on the power generation side. At the same time, only in the case of complete contracting, the income gap between power generation enterprises and the scenario without contracting contracts is the smallest, which further enhances the incentive role of power generation enterprises to actively participate in the market. The formulation of measures effectively stimulated the trading willingness of market players, fully released market dividends, and realized the orderly connection between the planning model and the market model.

3. Conclusion

This paper designs the medium and long term power plan formulation method under the market environment: based on the annual power forecast of non-operating power users, the demand for frequency modulation and peak regulation of the grid, and the reasonable income of the power generation enterprises as the boundary, calculate and distribute the basic base power of each power plant. The difference between the annual planned amount of electricity and the planned amount of electricity delivered shall be issued as the total transaction scale, and medium and long-term transactions shall be organized. If there is an uncontracted electricity, the remaining electricity is issued as the base electricity, and the distribution method is the same as the traditional planning mode. In terms of monthly decomposition of the annual electricity plan, the annual priority power generation is decomposed into each month based on the priority power generation of each month. The remaining planned electricity is decomposed into monthly priority power generation in proportion.

The paper analyses the reasonableness of the power plan formulation method and the effectiveness of connecting with the market. The higher the proportion of medium - and long-term contracts are not signed, the unit electricity cost of the user side increases, and the unit market-based power generation income of the power generation enterprise decreases. From the Angle of profit-seeking, both developers and users tend to get the maximum market returns, so both have the motivation to sign all the medium and long-term contracts, and the enthusiasm of market transactions has been greatly increased. It can be seen that the method for making power generation plans in the market environment proposed in this paper has a positive effect on encouraging market players to participate in trading, and realizing the orderly connection between the plan and the market.
