The proportion that renewable energy participates in the market transactions continues to increase.However,renewable energy has many characteristics such as strong volatility,poor prediction accuracy and so on,causing uneven distribution of cardinal electricity quantity among renewable energy power plants,low consumption ratio of renewable energy and other issues.As a result,design of renewable energy power plants to participate in the electricity market trading bias settlement model is particularly critical.The method of substitute compensation for renewable energy is put up according to the present situation of the renewable energy.Firstly,the actual generation of the renewable energy plant should minus the beforehand contract generation and make sure the base power generation according to installed capacity of units.Then,the comprehensive unit price of the renewable energy power plant settlement is determined based on electricity quantity and electricity prices in market transaction,and the economic compensation for less power plants from excess power plants is calculated.Finally,a specific example is given to show that the method can make the power plant with a high market share to obtain high profits,while the monthly power transaction execution is guaranteed.
