“…On the reliability assessment side, currently, we assume different customers with pools are independent of each other. However as discussed in [41], some factors can cause a dependency between failures of individual customers. Weather conditions such as sudden freezing temperature, and power system condition such as abnormal voltage and abnormal frequency, and cyber attacks [42] are among the reasons that can cause dependency between switches.…”

This paper introduces a conceptual framework, a capacity assessment method, and a data-driven optimization algorithm to aggregate flexible loads such as in-ground swimming pool pumps for reliable provision of spinning reserves. Enabled by Internet of Things (IoT) technologies, many household loads offer tremendous opportunities for aggregated demand response at wholesale level markets. The spinning reserve market is one that fits well in the context of swimming pool pumps in many regions of the U.S. and around the world (e.g. Texas, California, Florida). This paper offers rigorous treatment of the collective reliability of many pool pumps as firm generation capacity. Based on the reliability assessment, an optimal scheduling of pool pumps is formulated and solved using scenario-based approach. The case study is performed using empirical data from Electric Reliability Council of Texas (ERCOT). Cost-benefit analysis based on a city suggests the potential business viability of the proposed framework.

“…For example, a single lightning strike can cause trip-outs of two circuits on the common tower, while a tornado or a storm can cause outages of adjacent lines in a common corridor. In addition, one can evaluate Nk contingencies but the system solution will be computationally expensive and considerably time-inefficient [19]. Thus, N -1 and N -2 contingencies are studied in the TS as a prerequisite to avoid the system from going into an emergency state.…”

Active distribution grids cause bi-directional power flow between transmission system (TS) and distribution system (DS), which not only affects the optimal cost but also the secure operation of the power system. This paper proposes a hybrid coordination method to solve the risk-aware distributed optimal power flow (RA-DOPF) problem in coordinated TS and DS. For operation risk evaluation, the weather-based contingencies are considered in both TS and DS. A hybrid coordination method is developed that entails analytical target cascading (ATC) and Benders decomposition (BD). Moreover, the risk-aware optimal power flow (RAOPF) in TS and risk-based security-constrained optimal power flow in DS have been performed using the BD method considering basic optimal power flow as a master problem, whereas N -1 and N -2 contingencies are considered as sub-problems. Different case studies are performed using the IEEE 30-bus system with generation reserves as a TS and a 13-bus system as a DS. The results demonstrate the efficacy of the proposed method.

“…Protection systems are expected to be both dependable and secure [6,17]. Missing operation of the protection system occurs if it fails to react appropriately to a situation it is designed to respond to and would be a shortfall of the dependability of the system.…”

“…Society is dependent on a reliable supply of electricity for its normal operation, and thus power outages can have severe consequences. Major blackouts are often due to multiple component outages, caused by environmental factors [1][2][3][4][5], and/or dependent failures such as protection system failures [6]. The increased probability of failure of one or more components in a short period of time due to extreme weather has been termed failure bunching, and models have been developed to capture such effects in power system reliability studies by using both analytical methods and Monte Carlo simulation methods [7][8][9][10].…”

Reliability of Supply and the Impact of Weather Exposure and Protection System Failures

Extreme weather is known to cause failure bunching in electrical transmission systems. However, protection systems can also contribute to the worsening of the system state through various failure modes—spontaneous, missing or unwanted operation. The latter two types of failures only occur when an initial failure has happened, and thus are more likely to happen when the probability of failure of transmission lines is high, such as in an extreme weather scenario. This causes an exacerbation of failure bunching effects, increasing the risk of blackouts, or High Impact Low Probability (HILP) events. This paper describes a method to model transmission line failure rates, considering both protection system reliability and extreme weather exposure. A case study is presented using the IEEE 24 bus Reliability Test System (RTS) test system. The case study, using both an approximate method as well as a time-series approach to calculate reliability indices, demonstrates both a compact generalization of including protection system failures in reliability analysis, as well as the interaction between weather exposure and protection system failures and its impact on power system reliability indices. The results show that the inclusion of protection system failures can have a large impact on the estimated occurrence of higher order contingencies for adjacent lines, especially for lines with correlated weather exposure.
