New bid structures for power exchange with modelling in ILP framework

Block bid were introduced in power exchanges to allow generators with high fixed cost component (start-up and shut-down cost) participate in the market. However, block bid has been designed with very simple structure. Rigid structure in block bid often leads to them being rejected paradoxically. With this factor as motivation, we present new bid structures which retains objective of block bid, but brings in more flexibility, resulting in more liquidity in market.
