Market-Based Redispatch May Result in Inefficient Dispatch
研究了统一价格日前电力现货市场在阻塞后进行再调度的机制，发现基于市场的再调度（MBR）在激励成本最小化时通常不如基于成本的再调度（CBR）高效，且可能降低整体福利。
In this paper we analyze a uniform price day-ahead electricity spot market that is followed by redispatch in the case of network congestion. We assume that the transmission system operator is incentivized to minimize redispatch cost and compare cost-based redispatch (CBR) to market-based redispatch (MBR) mechanisms. For networks with at least three nodes we show that in contrast to CBR, in the case of MBR incentives to minimize redispatch cost are in general not efficient in the context of our short-run analysis. This obtains both for pay-as-bid as well as locational marginal prices used for MBR compensation. As we demonstrate, moreover, in case of MBR the possibility of the transmission system operator to inefficiently reduce redispatch cost at the expense of decreased overall welfare can be driven both by the electricity supply side and the electricity demand side.Our results highlight a novel and important aspect regarding the design and the desirability of congestion management regimes in liberalized electricity markets.
