| dc.description.abstract | Abstract The Palestinian Territories depend on the Israeli side for 100% of their imports of fossil fuels and 87% of their imports of electricity are taken from Israeli electricity company (IEC) and simple part from neighbouring countries such as Jordan and Egypt. Because of this, the price of electricity in Palestine is very high relative to neighbouring countries. The electricity is distributed to the residential sector which takes the largest share of electricity then the industrial sector. Because of that high sourtage solar radiation, which reach up to 5.4 Palestine is utilizing renewable energy mainly PV and solar thermal system. In Palestine the PV system can be utilized in two main configuration. The first configuration is a stand-alone PV system which is commonly used in places that are not connected to the network. The second configuration is a grid connected PV system. In this project, we want to introduce an electrochemical batteries like lead acid batteries as a source of energy storage to the grid connected PV system. In order to increase the performance and stability of the system. PV syst software, HOMER and SAM are used in this project to perform the simulation. System Advisor Model (SAM) is used to perform the simulation in this project. HOMR and PV syst are used partially for perform some part of simulation. Different scenarios were studied. The first one was a 1 MW grid connected PV system and a 500 kW electrochemical batteries storage system with a capacity 3000 kWh and this storage energy was used at night. The energy that produce from PV system meeting the batteries before load and then if there is energy remained, it will carried over to the network. In the second scenario the size of grid connected PV system and storage system are the same size in scenario 1. But the period of discharge the energy storage is different. The discharge period became divided into mid-day and night and I made two options in this scenario, the first option is the energy produce from the PV system is deal with it as in the scenario 1. The second option is the energy that produce from PV system meeting the load before batteries and then if there is energy remained, it will carried over to the network. The last scenario was a 2 MW grid connected PV system and a 500 kW electrochemical batteries storage system with a capacity 5000 kWh and this storage energy was used at night. The energy that produce from PV system meeting the batteries before load and then if there is energy remained, it will carried over to the network. After comparing all the scenarios with each other, the best scenario is scenario 1, because its results relative to the economic indicator. It was as follows, the total energy production from system during 25 years is equal 3.61 × 10^7 kWh, the net annual savings in the first year were 1,126,150 ($) and the cost of energy production 4.5 (¢/kWh). Scenario 2, it was less performance, the amount of energy produced is less than scenario 1, which is equal 3.04 × 10^7 kWh under the same conditions. Scenario 3 is not preferred because it did not achieve the goal to be achieved from this study, which is to obtain greater benefit from the energy storage system. Although the amount of energy produced from the complete system was 7.24 × 10^7 kWh. However, the net annual saving in the first year was equal 1,848,956 ($). This saving if compared with the first scenario saving it was considered very small. | en_US |
