As Photovoltaic (PV) penetration level rapidly increases in the modern power systems, the adoption of energy storage systems (ESS) is a preferred option to control the rapid and unpredictable PV power fluctuations. It is desired to develop new reliability evaluation methods that can model and evaluate the reliability impact of these new entries. This paper has proposed an area risk based method that...
With increasing PV power penetration in the modern power grid, a cost-effective solution to address PV intermittency becomes more and more compelling. The ramp rate of PV power can reach 60% of its rated capacity in just 30 seconds. Energy storage is a technically feasible solution to suppress the adverse impacts of injecting intermittent power output with such a high ramp rate into the grid, but...
The deregulation of power systems allows customers to participate in power market operation. In deregulated power systems, nodal price and nodal reliability are adopted to represent locational operation cost and reliability performance. Since contingency reserve (CR) plays an important role in reliable operation, the CR commitment should be considered in operational reliability analysis. In this paper,...
The utilization of renewable sources in power generation and system deregulation are two major changes the power system are undertaking. Different evaluation models are needed in order to incorporate renewable generation in the existing power system analysis. In deregulated power system, the impacts of renewable generation penetration are not only on the physical operation, but also on economic operation...
