Applicability Evaluation

It is difficult for current technical standard to satisfy the development requirement of smart distribution network because the new systems of distribution generation and energy storage and the new requirement of distribution network. First, new requirement for technical standard is analyzed in this paper. Then, applicability evaluation model of technical standard in smart distribution network is built. At last, empirical research on applicability of the operational control specification of the interconnection of distribution generation to power grid is carried out. The results show that the evaluation method proposed in this paper is feasible and effective.

Home Energy Management

Buildings with solar photovoltaic (PV) generation and a stationary battery energy storage system (BESS) may self-sustain an uninterrupted full-level electricity supply during power outages. The duration of off-grid operation is dependent on the time of the power fault and the capabilities of the home energy management system (HEMS). In this paper, building resilience is quantified by analyzing the self-sustainment duration for all possible power outages throughout an entire year. An evaluation method is proposed and exercised on a reference house in California climate zone 9 for which the detailed electricity usage is simulated using the EnergyPlus software. The influence of factors such as energy use behavioral patterns, energy storage capacity from the BESS, and an electric vehicle (EV) battery on the building resilience is evaluated. Varying combinations of energy storage and controllable loads are studied for optimally improved resilience based on user preferences. It is shown that for the target home and region with a solar PV system of 7.2 kW, a BESS with a capacity of 11 kWh, and an EV with a battery of 80 kWh permanently connected to the home, off-grid self-sustained full operation is guaranteed for at least 72 h.

A method of evaluation for peak/off-peak price functions in energy storage technologies is presented. The method is particularly useful in statical optimization of the fundamental parameters required for planning energy storage plants. Its application permits to transform the original dynamic optimization problem into a statical equivalent problem, thus reducing considerably the computing time needed. This transformation introduces two additional parameters to be optimized using statical optimization methods, i.e., charging and discharging duration.
