Spinning reserve (SR) is one of the most important resources used by system operators to maintain system security, but excess amount of SR which goes against economy must be avoided. A new unit commitment model is proposed in the paper, which adds expected customer interruption cost (ECOST) into the objective function. Thus a pretty tradeoff between system security and economy can be achieved while...
Value-based reliability analysis needs to be addressed in transmission expansion planning in a competitive environment. This paper presents a new Value-Based Reliability Transmission Planning (VBRTP) process using a Multi-Objective Transmission Expansion Planning (MOTEP) approach. A so called Expected interruption COST due to transmission constraint (ECOSTTS) is proposed to measure, more accurately,...
Reserve plays an important role in maintaining power system reliability and security. It has practical significance and applicable value taking interruptible load for one kind of reserves to ensure power system reliability and optimize the resource in the electricity market environment. At present, interruptible load has participated in some reserve markets together with generator, but the existing...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
Distribution network reconfiguration provides an effective way to control the tie and sectionalizing switches in the system to give an appropriate connection for certain reasons. In this paper, the emphasis of distribution network reconfiguration is on enhancing the reliability of electric power supply so that customer interruption cost is minimized subject to system operational constraints. A simulated...
This paper deals with the problem of designing the optimum stand alone solar thermal power system (STPS) which achieves the minimum total cost and satisfies the required level of reliability. For this purpose, an optimization model is developed to enable the engineers to find the size of the collector area and the storage capacity which provide the lowest cost system when the costs of the subsystems...
