Selection of Pumps as Turbines Substituting Pressure Reducing Valves
Abstract Technical standards define operational limits for hydraulic parameters such as velocity or pressure. On this way, pressure control is a fundamental component for safe operation at water supply systems, mainly to reduce leakage, risk of disruptions and maintenance costs.

This study presents a hierarchical coordination framework where multiple VPPs interact with the DSO to optimize energy trades and flexibility offers. Each VPP aggregates DERs and DR, performing internal optimization, day‐ahead bidding, and assessing flexibility to reduce excess renewable generation and pollution.

RELIABILITY OF THERMO-MECHANICAL EQUIPMENT IN POWER PLANTS – ELEMENTS WITH HIGH FAILURE R [PDF]
Thermal power plants are complex systems with many inter-dependence links and several critical elements that condition the operation of the whole plant. Failure of critical elements such as feed water pump results in a general shut down of the whole unit.
