The price per kilowatt-hour of energy delivered by the electric power utility varies as the total power demand supplied to the region it serves throughout the day. To save money and protect power system equipment, it may be necessary to schedule the energy consumed during these periods of high/critical demand and higher pricing. In this project, a number of demand-side management strategies (DSM)...
As renewable sources are being added to the grid to meet the electricity demand of users everywhere, there is an optimization problem floating in the mix that, without being attended to, could waste not only power, but money as well. This problem, typically involving systems with two or more renewable energy installations, is known as power management and pertains to the appropriate time for power...
A few decades ago, the thought of using solar panels to save money on the power bill was inexistent. However, as advancements in renewable energy technology continue, adding renewables to one's home or business is becoming more and more beneficial. The prices of renewables such as solar panels and wind turbines has decreased drastically over the past couple decades. This is shifting their use from...
Dissolved gas analysis (DGA) and its key-gas ratios (C2H2/C2H4, CH4/H2, C2H4/C2H6) are the most widely used fault diagnostic tests for transformers. This technique monitors the concentration of various gases in transformer oil and uses it to interpret the type of fault. In this study, support vector machines (SVM) is proposed to classify and predict electrical faults in transformers depending on the...
The recent push for electrified vehicles, including both plug-in hybrid vehicles and pure electric vehicle may further increase peak electrical load if left unmitigated, resulting in more demand for generation and transmission capacities. Fortunately, PEVs can be treated as controllable loads or even power sources under extraneous situations for demand side management (DSM). Although centralized approach...
State estimator is crucial for on-line power system monitoring, analysis and control. With the increasing use of synchronized phasor measurement units (PMUs) in power grids, utilization of phasor measurements to improve the precision and observability of state estimator becomes imperative. However, for state estimation, the PMUs should be placed appropriately in the network. In this paper, a novel...
