英文要約Title: Solar Energy Technology R&D, Next-Generation Technology Development of PV Generation System, Development of PV Generation Forecast Technology (FY2010-FY2012) FY2010 Annual Report
The R&D of the first fiscal year of the first half of 5 year period was made in the following three parts: (1) Survey of of Power System Operation Planning Modelling with PV Generation forecast: Under the anticipated high penetration of variable renewable energy generation such as photovoltaic, the ultimate issue of supply demand balance should be evaluated and fixed in a power system operation planning and realtime operation, generation mix planning. Accordingly, the methodologies of power system planning and operation such as unit commitment planning, economic load dispatch and load frequency control were surveyed in a series of featured interes areas: emerging issues of asset and operation planning of a power system, competitive power market, penetration of distributed generation including PVs, activated demand, accommodation of generation forecast and its evaluation. (2) Specification of a power system operation planning model for the specification and evaluation of PV generation forecast technology: The specification was prepared in the two steps. The first step identified technologies to reinforce the demand-supply balancing capability of a power system. We develop the model specification of the identified technologies such as demand activation, and energy storage and EV charging for the demand-supply balancing model. In the second step, a methodology to calculate the demand-supply balancing requirement and indicator for its sufficiency were specified. (3) Development of a Power System Model with High PV Penetration: A power system model was developed including the demand technology models specified in the previous study in line with the major parameters of power demand and supply conditions identified in the Energy Basic Plan of METI (2010). The model is featured with assumption of 53GW penetration of PV and new demand technologies such as an EV, a heat pump water heater and a battery. The 53GW PV requires the additional balancing capability of the power system due to its generation variation. Each demand technology offer additional balancing capability through two types of managements, a day-ahead scheduling and real time control We verified the model in the following steps: 1) verification against the original demand-supply condition of the Energy Basic Plan and 2) verification of the indicators of “hours with insufficient balancing capability” and “required generation curtailment of PV generation” under parametric case studies. With the above achievement of the first year, it is recognized that the targets of the first year were completed and we are ready to proceed to the schedule of the second year.
