Three-level secondary negawatt trading market mechanism with capability of congestion management

Modern power markets are witnessing various energy transactions, and the participants are focusing on different objectives like energy cost, profit, and environmental concerns as key parts of their strategy. In recent years, producers, prosumers, and other participants found ways to act freely in the grid and maximise their profit. By using negawatt trading (selling the right of buying to other participants), consumers will find a way to choose their role (seller, buyer, or negawatt trader) as they desire in the market and can join the market to maximise their utility function. A three-level secondary market is proposed that would work besides the day-ahead market. In the designed market, the network manager first determines the value of negawatt for each time in each region by considering the network conditions, and then by exchanging the information specific to each group, buyers and sellers have an opportunity to trade negawatt as much as they desire with the specified price in each time. The designed market also provides a mechanism to control the exchanges between different areas, which allows the network manager to control the grid conditions. The results show that the introduced market can be profitable for each participant including the DSO and work without interfering with the day-ahead market process.
