In smart grid power system operation frequency regulation is one of the most critical tasks to maintain the power balance in a power grid. This paper presents the coordination of frequency regulation in non-synchronous AC system connected via multi-terminal direct-current (MTDC). The frequency regulation study is carried out by scheduling the reference power setting at the DC grid converters along...
In this paper, a strategy has been proposed to find optimal number of electric vehicles (EVs) that can be safely integrated to distribution network without violating the networks constraints. Next in the study, we assess the impact of contingency in charging of electric vehicles (EVs) on the distribution grid. The distribution of EVs for charging from contingent feeder to nearby feeders is investigated...
This paper discusses the impact of several operating conditions and design considerations on power balancing in a MTDC system. A five terminal MTDC system is analyzed for instantaneous power balancing and variations in DC bus voltages by considering one of the terminals in constant power mode while others in DC voltage droop control mode. The study explores how the deviations in power/voltage are...
This study discusses the use of time-delayed remote signals available through phasor measuring units (PMUs) for low-order controller design in order to stabilise the power oscillations in the range of 0.3–0.42 Hz between two areas. In the proposed approach, first synchronisation measures are determined among the group of generators located in two areas. Then, an index that characterises the joint...
In this paper, optimum location for charging of electric vehicles (EVs) and its charging strategy in a modified IEEE-34 distribution system is proposed. To determine the optimum location, a 24 hour load demand is varied at given junction nodes and the corresponding voltage sensitivity indexes are determined. These indexes are derived from the inverse Jacobian matrix from the Newton-Raphson power flow...
