Energy storage-based packetized delivery of electricity
| DWPI Title: Method for facilitating energy storage-based packetized delivery of electricity to charge grid storage system for such as electric vehicle charging, involves sizing the energy storage systems with power and energy ratings at each node on the basis of expected load and local generation |
| Abstract: Systems and methods for Energy Storage-based Packetized Delivery of Electricity (ES-PDE) are disclosed that are radically different from the operation of today's grid. Using ES-PDE, the loads are powered by the energy storage systems (ESS) the majority of the time and only receive packets of electricity periodically to charge the ESSs. Therefore, the grid operators can schedule the delivery of electricity packets to utilize the existing grid infrastructure. Since the customers are powered by the co-located ESSs they are not impacted by the grid operation in short term. Therefore, when grid outages occur, the customers still have power for some time, giving the grid more time to be fully restored. |
| Use: Method for facilitating energy storage-based packetized delivery of electricity to charge grid storage system for such as electric vehicle charging. |
| Advantage: By using energy storage-based packetized delivery of electricity, grid operators can schedule delivery of electricity packets to the energy storage system of customers in a manner that fully utilizes the grid infrastructure, and minimizing the system operating cost and neglecting or deferring the need for infrastructure upgrade. |
| Novelty: The method involves sizing the energy storage systems with power and energy ratings at each node on the basis of expected load and local generation. The delivery of energy packets is scheduled on the basis of the parameters selected from a group with grid constraints, generation constraints, energy storage constraints, system operating costs and energy storage degradation. The switches that route scheduled energy to energy storage system of the energy storage systems is controlled at the correct time to enable packetized delivery of energy. The switches that route unscheduled energy to the energy storage systems at the correct nodes is controlled at the correct time to enable packetized delivery of energy. |
