4 Microgrid Any localized grid with its own power generation resources, loads and definable boundaries and acts as a single controllable entity qualifies as a microgrid. A power grid that: 1. Can operate independently and 2. Operate in conjunction with the area's main electrical grid

8 Module Types Monocrystalline - PV modules are the most efficient and most expensive panels currently available. Polycrystalline - Most commonly seen type of PV modules Thin Film - Traditionally Thin-film has always been cheaper but less efficient than conventional c-si technology.

11 Temperature The output power of a solar module is affected by the temperature of the solar cells. In Crystalline PV modules this effect can be as much as 0.4% for every 1 degree C variation in temperature. Thin Film Module Temperature Coefficient of P MPP is 0.29%/ o C. PV modules actually function better at colder temperatures. Linear (Thin Film) Linear (Multicrystalline Si)

24 Microgrid Master Controller - MMC Master controller for microgrid systems Scaled platform for small to large installations Integrates all energy sources Optimizes production of energy

25 Microgrid Master Controller Features Feature Description Monitoring and Control-User Interface Asset Optimization Distributed Resource Dispatch Grid Import/Export Power control Includes system visualization and user interface for manual or automatic control of the distributed energy resources. Based on a number of different parameters, such as minimizing fuel cost, optimizing engine operation, or maximizing system reliability. Photovoltaic (PV) system, energy storage system (ESS) and generator sets are controlled from the MMC. Regulates the amount of real and reactive power contributed to the microgrid from the available utility service based on a programmable set point. Black Start Load Management Configured to coordinate the available generation to energize the microgrid from a de-energized (black) state. Sequencing loads to ensure voltage and frequency are kept within acceptable ranges. Actively control the powered loads to ensure the system is not overloaded (load shed signal will be triggered to remove low priority loads. As load falls below a given set point a signal will be triggered to add additional loads.)
