Evaluation Of Distributed Power Supply In Energy Internet Background

In the "The 13 th Five-year" plan,China clearly put forward to vigorously develop renewable energy,improving the proportion of clean energy.Although the development of distributed power in China has made gratifying achievements,but still faced with the business model is not perfect,the policy implementation is not in place,renewable energy consumption is difficult and low investment enthusiasm.At present,there is not a suitable assessment method for the true value of distributed power supply,leading to investors in the evaluation of distributed power projects lack of assessment tools,lack of investment confidence.Energy Internet will be a high degree of integration of energy and information technology,relying on energy flow and information flow of the two-flow fast exchange,breaking the traditional energy production and use of distributed power for large-scale development provides an effective solution.Based on historical data such as construction data,operation data,grid data and customer data,it can effectively solve the problem of location optimization of the distributed power supply in the construction period,effectively reduce the operation and maintenance costs of the equipment,and forecast load and power Means to improve their economic and forward-looking energy supply services.Renewable energy distributed generation under the energy Internet system can effectively reduce the development and operation and maintenance costs and solve the problems related to consumption and grid connection.In this paper,a new perspective on the value of distributed power in the context of the energy Internet is evaluated,combining with the development of energy and energy Internet.Firstly,this paper summarizes the dynamic research of energy Internet,the economic benefit analysis of distributed power and the value evaluation methods,analyzes the status of energy Internet and distributed power supply at home and abroad,summarizes the experience and provides the theoretical basis for the work of the paper;Second,through the connotation of energy Internet,distributed development of the status quo and distributed power business model to study the distribution of power in the energy Internet system,the value of the source;third,from the political.Economic and technical aspects of the three factors of distributed power value,and the applicability of the traditional three valuation methods to study,combined with comprehensive evaluation method to determine the value of distributed power evaluation research ideas;Fourth,the distributed value is divided into two parts: the value to the user and the value to the power grid.The user side and the economic value index of the power grid are set up respectively.The cost-benefit model is built.Finally,the value evaluation model of the distributed power is established.Sensitivity analysis.Fifthly,microgrid is the initial stage of the development of energy Internet.In this paper,we separately calculate the economic value of distributed power access and micro-grid access grid separately,and quantitatively evaluate the effect of energy Internet on distributed power The risk of the distributed power investment is analyzed from the aspects of policy and regulation risk,market risk and stakeholder risk,and the corresponding risk coping mechanism is put forward.Through the research of this paper,the following innovative results are obtained: First,the research has obtained the distributed power value composition way;Second,has given the improved distributed power source value appraisal method;Third,through the example confirms the energy The Internet 's Contribution to the Distributed Power Supply.
