Abstract: Systems and methods for optimizing energy consumption in multi-energy sources sites are provided. These techniques include developing a real-time model and a virtual model of the electrical system of a multi-energy source site, such as a microgrid. The real-time model represents a current state of the electrical system can be developed by collecting data from sensors interfaced with the various components of the electrical system. The virtual model of the electrical system mirrors the real-time model of the electrical system and can be used to generate predictions regarding the performance, availability, and reliability of cost and reliability of various distributed energy sources and to predict the price of acquiring energy from these sources. The virtual model can be used to test “what if” scenarios, such as routine maintenance, system changes, and unplanned events that impact the utilization and capacity of the microgrid.

Abstract: A method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of an energy planning process (EPP) system which can be used to plan a voltage control and conservation (VCC) system applied to an electrical distribution connection system (EEDCS). The EPP system plans modifications to the EEDCS as a result of operating the VCC system in the “ON” state, in order to maximize the level of energy conservation achieved by the VCC system control of the EEDCS. The EPP system may also identify potential problems in the EEDCS for correction.
