| Abstract | This thesis address developing a two-layer interactive power trading for 115kV day ahead power pool in Eastern Economic Corridor area located in Thailand. The basic concept is decentralizing the electricity market in Eastern Economic Corridor area, which including Chachoengsao, Chonburi, and Rayong provinces. The 115kV day ahead power pool model is devised by using the realistic data of PEA transmission system, small power producer cogeneration capacity, large industrial customer demand, and propose a two-layer interactive mechanism for decentralizing energy trading. The two-layer structure of 115kV day-ahead power pool model in EEC area consists of the bottom layer and the upper layer, which each layer is the hybrid market model combined with the characteristics of the Pool model (Day-ahead market) and Bilateral contract model (Physical Forward market). The bottom layer is designed for energy trading inside industrial estates and the upper layer is designed for energy trading among industrial estates. The interaction mechanism plays a key role in this thesis: The energy surplus and shortage of each industrial estate after trading at the bottom layer will be traded at the upper layer among EEC-ISO. In a power system with a deregulation environment, all power producers and customers use the common transmission network to transfer power to end-users. And in the open-access framework, all parties seek to buy power from the less expensive source to get the high-profit margin, which without violating the system security limit. In deregulation markets, the auction mechanism is the most common mechanism to match the active power supply and demand because the market equilibrium can be found with ease and transparency. The auction mechanism is presented to discover market clearing price and market clearing quantity in each layer. The bottom layer is used a single-sided auction mechanism different from the upper layer, which is used a double-sided auction mechanism. For energy trading in each process, transmission congestion will be checked before the transaction. This research also describes a method for determining the available transfer capability (ATC) between any seller and buyer in the transmission system at the upper layer model. This model simulates the operation by using Power World Simulator. The simulation result illustrates that 115kV Day-Ahead Power Pool model is having a benefit for everyone that is involved. |
