In this paper a real-time short-circuit calculation method for large-scale distribution systems with a high penetration of distributed generators is proposed. Recent years have witnessed increasing penetration of distributed generators. Thus, distribution systems have become active, where the fault current flow is no more straightforward. Additionally, modern distributed generator's models differ...
In this paper, the relationship between accuracy of Customer Baseline (CBL) calculation and efficiency of Peak Time Rebate (PTR) program for residential customers is investigated. To perform the analysis, well-established CBL calculation methods, HighXofY(NYISO), LowXofY, MidXofY, exponential moving average(ISONE) and regression are first introduced and then utilized to calculate the CBL. A dataset...
Due to the increasing utilization of lightweight gas turbine units and renewable energy resources, the power grid is shifting towards a situation with less inertia, which results in the decline in system primary frequency responses and threatens the grid reliability. However, the capability of fast-acting storage devices to provide frequency response brings the operational flexibility into system...
To enable greater innovation in power systems, our research seeks to create entirely fictitious synthetic power system networks that capture the functionality, topology, and defining characteristics of the actual U.S. transmission system, and thus provide realistic test cases for research, without revealing any sensitive information. Creation of these models relies only on publicly available data...
Demand response (DR) is a key component of smart grids that can bring a lot of benefits to power system operators and customers. Most literature on DR focuses on the operation, control and planning aspects of “smart grids”, while its impact on, and potential for improving system reliability is less studied. DR can mitigate the operational limit violations by changing the load profile when the reliability...
The orderly transition of the current electricity grid to a smarter grid facilitates the demand side to increasingly play a proactive role. Enabling technologies within the smart grid framework play a crucial role in alleviating systemic risks associated with capacity shortages, electricity price volatility and congestion by controlling end user electricity consumption through demand response (DR)...
