- Residential micro-grid can reduce the household's electricity expense as well as shift the electricity demand from peak time to valley time. Optimal management of a typical residential smart micro-grid is conducted using a proposed model in the present study. In the optimal management, the real-time pricing mechanism, feed-in-tariff for Photovoltaics (PV) power as residential electricity generators, and residential appliances are considered. Four scenarios are studied and the result shows that the real-time pricing mechanism shifts effectively the electricity consumption from time peak time to valley time, and different feed-in-tariff of Photovoltaic (PV) can shift the energy consumption of micro-grid between periods with strong solar irradiation and weak solar irradiation.

- Promoting the penetration of distributed photovoltaic systems (PV) at the end-user side is an important and urgent task. This study aims to evaluate the promotion impact of the response capability of smart home consumers on the distributed PV penetration using non-cooperativegame theoretical analysis. In the analysis, the Nash equilibrium can be found for consumers with different levels of demand response capability in an electricity market with real-time pricing (RTP) mechanism under different PV installed capacities and battery capacities. As a case study, 5 levels of consumers' response capability, 32 combinations of PV installed capacities and battery capacities were analyzed and inter-compared using the developed model. The results show that: (i) the consumers with higher response capability are able to accept larger PV capacity because the marginal revenue of new installed PV for smart consumers decreases much more slowly compared to that of a common consumer; (ii) the consumers with higher response capability need less batteries to promote PV economic acceptability; (iii) the consumers with higher responsecapability can meet the electricity demand in real-time with least expenditure, so they get more ultimate benefit from the games.
