An electric proptdsion vehicle designm! to transport cargo in support of a piloted expedition to Mars will require electrical power in the range of megawatts. This paper summarizes an evaluation of various megawatt-class power processing unit (PPU) design and technology options for high-power nuclear electric propulsion (NEP) vehicles using turboalternators and a d v a n c e d magnetoplasmady n...

This paper studies optimal relational contracts when the value of the relationship between contracting parties is not commonly known. I consider a principal-agent setting where the principal has persistent private information about her outside option. I show that if the principal has the bargaining power, she wants to understate her outside option to provide strong incentives and then renege on...

one of the significant strategies of the power systems is economic dispatch (ed) problem, which is defined as the optimal generation of power units to produce energy at the lowest cost by fulfilling the demand within several limits. the undeniable impacts of ramp rate limits, valve loading, prohibited operating zone, spinning reserve and multi-fuel option on the economic dispatch of practical p...

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...
