Research On Bidding Strategy Of P2P Energy Trading Based On Market Evaluation Between Households In Microgrid

In recent years,with the continuous development of social economy,vigorously developing renewable energy including distributed photovoltaics has become a strategic choice for China to guarantee energy security,control environmental pollution,and respond to environmental climate change.Microgrid is considered to be an effective way to integrate distributed renewable energy for power management.Establishing a distributed generation market(DGM)in the microgrid to conduct peerto-peer(P2P)energy trading between prosumers to eliminate the photovoltaic energy generated by the market means to improve the utilization rate of photovoltaics and solve the problem of photovoltaic subsidies.This paper focuses on the market-based P2P energy trading bidding strategy among microgrid prosumers,summarizes the research status of domestic and international power market evaluation system and bidding strategy,and the market-based trading practice of distributed power generation,and establishes a comprehensive evaluation system for DGM multi-attributes.Based on this,a P2P energy auction model based on market evaluation is proposed.The validity of the model is verified by an example,and some research results are empirically studied.The main work of this paper is as follows:(1)The market-oriented trading framework and market entity model of micro-grid distributed generation are studied.It is proposed to build a heterogeneous hybrid network of distributed network architecture among microgrid users under the centralized power grid architecture to support the P2P energy transaction requirements among users in the distributed generation market.(2)A multi-attribute comprehensive evaluation system suitable for the distributed generation market was studied.From the three dimensions of power transaction reliability,transaction stability and transaction economy,the DGM multi-attribute comprehensive evaluation index system is established,and the improved eclectic fuzzy multi-attribute evaluation is proposed to comprehensively evaluate the power supply service level of each user.The credit and qualification constraints of market entities in the electricity market.(3)A P2P energy auction model based on market evaluation is proposed.Each power selling entity comprehensively considers the probability of winning the auction and the expected return after winning,and the product of the quotation and the market evaluation coefficient is used as the bidding bidding,and the example is used to verify the adjustment effect of the market evaluation mechanism on the auction result.Market entities improve their power supply services,thereby promoting the sound development of the power market.(4)Based on the rules of China’s distributed electricity market construction,the energy routing management system(ERMS)based on P2P energy trading algorithm was developed by computer technology.Based on the system,the P2P energy trading empirical analysis was carried out to verify the P2P energy auction.The correctness and practicability of the algorithm.
