Analysis of Complex, Multiple Electricity Markets

输电阻塞和地区之间不一致的市场规则可能会给消费者带来额外的成本，并危及互联电网的可靠性。有效的电网改进可以提高互联电网的输电能力，降低用户的阻塞成本。另一方面，不同的运营主体可能会有不同的市场结构和规则，以出清能源市场和应对拥堵。单个市场内部拥堵的处理方式对邻近市场的电力流动和价格有重要影响。该方案侧重于多个电力市场中阻塞管理规则的经济分析和电网改善决策的优化，以提高社会福利。对不同区域间协调的拥堵管理规则进行比较，以达到社会成本效益分析的目的。我们还将探讨不同的拥堵管理方法如何影响市场参与者的战略行为，以及多个市场互联电网中单个市场的市场均衡。结合大规模非线性电力系统的复杂特点，将全局优化技术应用于输电能力改善的经济价值分析。本研究的预期结果是通过系统化的方法改善电网决策，提高社会福利，并有效地进行区域间市场协调，消除区域间能源交易的障碍。

Transmission congestion and inconsistent market rules between regions can impose additional costs to consumers and jeopardize the reliability of interconnected grids. Efficient grid improvement can enhance the transfer capability of the interconnected grids and reduce the congestion costs to consumers. On the other hand, different operation entities may have different market structures and rules to clear energy market and handle congestion. How congestion inside an individual market is handled has important consequences on power flows and prices in neighboring markets. This proposal is focused on the economic analysis of congestion management rules and the optimization of grid improvement decisions for social welfare enhancement in multiple electricity markets. Different inter-regional coordination of congestion management rules will be compared for the purpose of social cost and benefit analysis. We will also explore how different congestion management methods affect the strategic behaviors of the market participants and the market equilibrium of an individual market in interconnected grids with multiple markets. Global optimization techniques will be applied to analyze the economic value of transmission capacity improvements incorporating the complex characteristics of large-scale nonlinear power systems. The expected results of this research are systematic methods to improve grid decisions for enhancement of social welfare and efficient inter-regional market coordination to remove barriers of inter-regional energy trading.
