讲座内容:

Natural gas and electricity systems are becoming increasingly coupled. Gas-fired units (GFUs) are replacing retired coal-fired power plants, and the power systems are more dependent on the ramping capability provided by GFUs. The GFUs’ power generation capability relies on the availability of gas supply, which is jointly determined by the capacity of gas suppliers and pipeline networks. However, the gas and electricity markets are operated separately. Consequently, the GFUs are forced to “represent” the entire power system to bid in the gas market: they must make forecasts regarding future gas consumption and bear the risk of improper contracts or being unable to meet generation schedules due to occasional insufficient gas supply. When facing larger shares of renewable energy and more-frequent gas network congestions, the current market framework is particularly unreliable and inefficient, as well as economically unfriendly to the investors of the GFU assets. In this presentation, we try to develop a framework that can integrate the two markets. By properly pricing the scarce resources (e.g., gas transmission capacity), the joint market can help allocate the resources more efficiently while satisfying the demands. Moreover, a more forward-looking day-ahead market clearing framework is presented by considering the uncertainty brought by renewable energy. The formulation and algorithm of the proposed joint market model will be presented, as are some case studies.
