Research On The Consumption Of Wind Power In Thermal Power Plants Based On Game Theory And Blockchain

With the rapid development of renewable energy such as wind power,there has been a serious abandonment in China.It not only directly causes the waste of available energy and economic losses,but also affects the confidence of the development of the entire wind power industry,and even brings more unpredictable negative effects.The dilemma of wind power consumption needs to be resolved urgently.In the context of the high incidence of wind abandonment in northeast,north and northwest China where wind power is mainly distributed,the paper researches on the disposition of additional heat source to absorb abandoned wind in thermal power plants: It is proved that reasonable collocation of additional heat sources in thermal power plants can promote the consumption of wind power through case study;Based on Game Theory,the paper systematically analyzes the feasibility of power generation rights trading between thermal power plants and wind power plants from the perspective of trading participants,and rationally designs the power generation price pricing mechanism to facilitate the signing of the agreement between the two parties;On the basis of signing the transaction agreement,the paper explores the use of Blockchain technology to realize the entire wind power consumption transaction.The transaction case in the constructed 34-node power flow calculation system shows that the Smart Contract can improve the fairness,efficiency and safety of the transaction.The details include:(1)The paper expounds the severity of the abandoned wind phenomenon in China,the reasons for a lot of abandoned wind is proposed,and further summarized the main methods of eliminating winds at present.Combined with the research status at home and abroad,it proposes to apply Blockchain technology to thermal power plants for wind power consumption.In the power generation trading,the efficiency and security of the transaction are improved.(2)Analysis is made on the current scheme of installing additional heat sources for thermal power units to achieve the purpose of wind power absorption.The model construction and case analysis verify the effectiveness of the thermal power plant configuration of the heat storage tank to eliminate the wind.And referr to the literature,taking the heat storage tank as an additional heat source in the thermal power plant as the research object,the mechanism of the thermal power plant to absorb wind power is discussed.(3)In the above scheme of configuring the thermal storage tank in the thermal power plant,based on the non-cooperative game and the cooperative game theory in the game theory,the game mechanism analysis and design of the wind power consumption of the thermal power plant is carried out,and the feasibility of the transaction is systematically analyzed.Rationally design the power generation price pricing mechanism to segment the remaining profit of the cooperation,and promote the parties to conclude a deal and sign an agreement.(4)There may still be a transaction default after the agreement was signed between the two parties,based on the similarity and applicability of the Blockchain technology and the energy Internet concept,a power generation rights transaction management center with weak centralization characteristics was proposed to realize the entire wind power consumption transaction.In the scheme,a 34-node micro-grid power flow calculation system is constructed,and the case of power generation right transaction between thermal power plant and wind power plant is analyzed based on the Smart Contract.It is proved that the method can realize the whole wind power consumption transaction at the same time.Smart Contract can solve the trust problem of both parties,improving the efficiency and security of the transaction,and reducing the transaction cost.
