Abstract

Congestion is a limitation in the transmission or a network when certain constraints are violated, resulting in inability to deliver power supply to the load at low cost. Congestion can lead to uncontrolled loss of load, resulting in cascading outages. Thus, the management of congestion is necessary in electrical industry and is extremely important. Different methods of congestion management are discussed in literature, and the paper focuses on economical and market-based methods. These market-based methods include auctioning, market splitting, counter trading, redispatching, demand response, and zonal and nodal pricing. The paper aims at manipulating the power flow using economical forces and substitutes to utilize the transmission parameters to the fullest. The paper also suggests that more than one method can be used within a country and/or when exchanging power between borders. It compares the congestion management technique used in different developed countries.


Description

Redefining of the electricity industry has led to the transition from vertically-oriented electricity structure to the deregulated electricity market. This transition has led to the development of new problems, typically congestion in the transmission networks (Yusoff et al., 2017). Congestion or bottleneck is a limitation in the transmission or a network when certain constraints are violated, resulting in inability to deliver power supply to the load at low cost (Kumar et al., 2005). In order to tackle this situation, congestion management techniques have been implemented. There are several congestion management techniques, which can be characterized into nontechnical and technical, as shown in Figure 1 (Mwanza and Shi, 2006; and Karthika and Paul, 2015).
