Abstract: Methods for implementing power delivery transactions between a buyer and a seller of electrical energy supplied to an electrical grid by an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility are provided. Estimated total potential output of the RES is compared to a point of grid interconnect (POGI) limit to identify potential RES overgeneration, and the buyer is charged if potential RES overgeneration is less than potential overgeneration during one or more retrospective time windows. The method provides a basis for the RES-ESS facility owner to be paid for an estimated amount of energy that did not get stored as a result of a grid operator not fully discharging an ESS prior to the start of a new day.

Abstract: The accuracy of photovoltaic simulation modeling is predicated upon the selection of a type of solar resource data appropriate to the form of simulation desired. Photovoltaic power simulation requires irradiance data. Photovoltaic energy simulation requires normalized irradiation data. Normalized irradiation is not always available, such as in photovoltaic plant installations where only point measurements of irradiance are sporadically collected or even entirely absent. Normalized irradiation can be estimated through several methodologies, including assuming that normalized irradiation simply equals irradiance, directly estimating normalized irradiation, applying linear interpolation to irradiance, applying linear interpolation to clearness index values, and empirically deriving irradiance weights. The normalized irradiation can then be used to forecast photovoltaic fleet energy production.

The radial network interconnects the buses with the distribution lines in a tree-like manner. A bus has a link to at least two distribution lines. The bus voltages and distribution line currents are determined by a processing circuitry configured to receive a Branch Matrix (BM), iteratively determine currents for the distribution lines and voltages for each of the buses until a difference is below a predetermined tolerance, and output final bus voltages and final distribution line currents. The circuitry iteratively determines the currents by determining a current matrix (CM) using the BM, and by determining the currents for the plurality of distribution lines in a zig zag manner over the matrix elements in the CM. The system finds a solution using fewer iterations than the backward forward sweep method.
