【摘要】：隨著我國電力市場體制改革和電源發(fā)展方針的推進,水電將逐步走向市場成為競爭主體,水電競價策略逐漸成為電力市場研究的熱點之一。國內外學者關于于在電力市場下火電廠競價上網(wǎng)和自優(yōu)化運行的文章較多,而對水電廠的研究相對較少。同時,寡頭壟斷市場是介于壟斷競爭與完全壟斷之間的一種比較現(xiàn)實的混合市場,本文將研究寡頭壟斷市場類型下水電廠策略性競價問題,以期為發(fā)電側水電廠競價策略提供理論依據(jù),也為可再生能源進入市場參與競價提供參考。本文在查閱國內外文獻的基礎上,首先對國內外電力市場研究現(xiàn)狀進行了總結,并簡單介紹了電力市場類型、水電傳統(tǒng)調度理論及模型、市場力及其相關理論,及分析了影響水電廠競價策略的主要因素;其次,針對市場結構中存在市場力的情形下,結合各發(fā)電廠成本信息非共同信息問題,以各電廠單臺機組的簡化問題入手,基于古諾模型建立了多個發(fā)電廠不完全信息的競價模型,通過解析模型納什均衡解生成發(fā)電廠的競價策略,分析了市場需求、成本信息等參數(shù)對均衡產量的影響。然后,進一步以各電廠多臺機組的復雜情形。并結合算例,研究了市場中擁有10個電廠情形下各發(fā)電廠商的競價問題。最后,進一步探索水電廠未來時段售電效益與當前時段售電效益兩者間的均衡問題,建立了考慮余留效益的水電廠競價模型,研究了水電廠的余留效益對競價策略的影響,得到了一些有效的結論。水電廠在進入市場競價的過程中,由于其自身特性,必定有許多有別于火電廠的思量。本文對水電參與競價問題進行有益嘗試,獲得了一些有意義的結果。然而,在發(fā)電側的競價過程中,還需要進一步研究和完善水電廠競價理論。這對于電力改革的推進,健康市場的運行具有重要的意義。
[Abstract]:With the reform of power market system and the promotion of power supply development policy, hydropower will gradually move towards the market and become the main body of competition. The strategy of hydropower bidding has gradually become one of the hotspots in the power market. There are more articles on bidding and self-optimizing operation of thermal power plants in the power market, but there are few researches on hydropower plants. The oligopoly market is a kind of realistic mixed market between monopoly competition and complete monopoly. This paper will study the strategic bidding problem of hydropower plants under the oligopoly market type. In order to provide theoretical basis for bidding strategy of hydropower plants on the power generation side, and to provide a reference for renewable energy to enter the market to participate in bidding. Based on the reference of domestic and foreign literature, this paper summarizes the current situation of domestic and foreign electricity market research. It also briefly introduces the types of electricity market, the traditional dispatching theory and model of hydropower, market power and its related theories, and analyzes the main factors that affect the bidding strategy of hydropower plants. Secondly, in the case of market power in the market structure, According to the problem of non-common information of cost information in power plants and the simplification of single unit in each power plant, the bidding models of incomplete information of many power plants are established based on Cournot model. Based on the bidding strategy of generating power plant with Nash equilibrium solution, the influence of market demand, cost information and other parameters on equilibrium output is analyzed. Then, the complex case of multiple units in each power plant is further taken into account, and an example is given. In this paper, we study the bidding problem of power generation firms under the condition of having 10 power plants in the market. Finally, we further explore the equilibrium problem between the benefit of power sale in the future period of hydropower plant and the benefit of selling electricity in the current period. In this paper, a bidding model of hydropower plant considering residual benefit is established, and the influence of residual benefit of hydropower plant on bidding strategy is studied, and some effective conclusions are obtained. There must be many considerations different from those of thermal power plants. In this paper, a useful attempt has been made on the participation of hydropower in bidding, and some meaningful results have been obtained. However, in the bidding process on the generating side, It is also necessary to further study and improve the bidding theory of hydropower plants, which is of great significance for the promotion of electric power reform and the operation of healthy market.
