Sentence examples for operating zones from inspiring English sources
This paper proposes improved DE algorithms for solving economic load dispatch problems that take into account nonlinear generator features such as ramp rate limits and prohibited operating zones in the power system operation.
This paper presents the design and application of an efficient hybrid heuristic search method to solve the practical economic dispatch problem considering many nonlinear characteristics of power generators, and their operational constraints, such as transmission losses, valve-point effects, multi-fuel options, prohibited operating zones, ramp rate limits and spinning reserve.
Feasible operating zones of the tested system under different DC terminal voltages are calculated.
Case 2: Here prohibited operating zones of hydro plants and valve point loading of thermal generator are considered.
A microgrid may also be divided into several predefined operating zones that are autonomously independent while operating in a coordinated manner.
In case of variable head hydrothermal system, multi-reservoir cascaded hydro plants having prohibited operating zones and thermal units with valve point loading are used.
where m represents the number of prohibited operating zones of j the generator in area i. ( {mathrm{P}}_{ij, m-1}^u ) is the upper limit of (m − 1) th prohibited operating zone of j the generator in area i. ( {mathrm{P}}_{ij, m}^l ) is the lower limit of mth prohibited operating zone of j the generator in area i.
The determination of operating zone is a complex and time-taking process.
Additional constraints such as the ramp-rate limit and prohibited operating zone for generators, as well as network security are also considered.
