Research on local consumption method of distributed photovoltaic generation for benefits of multi parties based on blockchain

Abstract

With the continuous growth in the proportion of distributed photovoltaic generation installed in rural distribution networks, some problems such as abandoning solar energy and increasing voltage fluctuation have become more and more prominent. In order to increase the local electricity consumption of the photovoltaic generation, the incentive mechanism using an optimal internal electricity price is proposed with blockchain technology. Some information is collected and stored in the blockchain network as scoring indicators. A comprehensive scoring strategy for photovoltaic generation companies to consumers is established. The optimal internal electricity price is set by maximizing comprehensive revenue of the companies and the consumers. The time-shiftable load plan can be made for the consumers based on the price and actual load constraints. The simulation result shows that the comprehensive revenue is increased, and the local electricity consumption rate of distributed photovoltaic generation is significantly raised after the incentive mechanism is implemented with the internal electricity price, and the feasibility of the blockchain technology is verified for the mechanism.
