This paper presents a new probabilistic approach of the real-time state estimation on the micro-grid. The grid is modeled as a factor graph which can characterize the linear correlations among the state variables. The factor functions are defined for both the circuit elements and the renewable energy generation. With the stochastic model, the linear state(More)
Today, the family of Hawaiian Electric utilities, consisting of Hawaii Electric Light Company (HELCO) on the Big Island of Hawaii, Maui Electric Company (MECO) on the islands of Maui, Molokai and Lanai and Hawaiian Electric Company (HECO) on the island of Oahu, are contending with PV penetrations in excess of 20 percent during high electricity demand days(More)
Solar irradiance forecasting is an important problem in renewable energy management where any dips in solar energy generation must be made up for by reserves in order to ensure an uninterrupted energy supply. In this paper, we study several data mining methods for short term solar irradiance forecasting at a given location. In particular, we apply linear(More)
