CANCELLED!!!! Battery energy storage systems for supporting electrical power distribution networks availability in Palestine

Abstract: The Palestinian electricity grid faces significant challenges concerning ampacity limitations within its electrical network due to the current political situation. These limitations are particularly problematic during peak demand periods when the current demand exceeds the network’s capacity. Furthermore, shortages in electrical supply, exacerbated by regional and geopolitical factors, often strain the network, leading to inconsistent power availability in certain areas. In addition to ampacity limitations and supply shortages, the Palestinian electricity grid also grapples with the challenges associated with integrating new PV system installations into the grid. The current electrical infrastructure often lacks the capacity and flexibility to efficiently incorporate these new energy resources. This integration requires significant upgrades to the existing topology of the grid to be capable of handling bidirectional energy flows, especially as IEC does not accept reverse power flow at the injection points. Moreover, the intermittent nature of solar power necessitates the development of robust energy storage solutions to ensure stability and reliability. Thus, integrating renewable energy resources into electrical distribution networks necessitates using battery energy storage systems to manage intermittent energy generation, enhance grid reliability, and prevent reverse power flow. However, the intermittent energy generation from RE sources makes it necessary to have a battery energy storage system to control the supply, prevent reverse power flow, and enhance the grid’s voltage. Moreover, in some situations, BESS can support loads in the case that the main power supply cannot fulfill these loads. This lecture shows a real case of integrating battery energy storage systems into an electrical power distribution network with a capacity of 25 MVA/33 kV capacity with 7 MWp photovoltaic plants.
