| The worsening of energy depletion and environmental pollution has made the utilization of new energy become one of the crucial measures for sustainable development.The rapid exploitation of intermittent energy such as photovoltaic power generation,wind power generation and electric vehicle in power industry reflects our emphasis on ecological environment protection and comprehensive energy utilization.With the accelerating pace of electricity market reform,load side resources can participate in electricity market transaction,which is beneficial to the coordinated scheduling and the construction of economic operation.Various intermittent energy and active loads have great potential in power market participation and service value of grid,while the lack of market integration and trading mechanism has restricted its development at present.This article aims to study the market mechanism suitable for various intermittent energy and active load,which will be helpful to the improvement of resource allocation level and the foundation of competitive multi-party power transaction pattern.This paper first analyzes the characteristics and impacts of various intermittent energy sources and active load on power grid operation.Secondly,research on the contract market.Then this paper studies the trading mechanism of active load.On the basis of analyzing the strategy of active load reduction contract quotation,this paper innovatively proposes a bi-level optimization model that load aggregator integrates active load reduction contracts and participates source-load interaction.Finally,this paper builds the trading mechanism of the day-ahead energy market for various intermittent energy sources and active load.By introducing load aggregator for the integrated management and market bidding,it involves market clearing modeling and self-bidding scheduling.Case study shows the effect of the model built in this paper on the market price leverage. |
